Published: February 2021

Abstract
The basin of Nansihu lake is dominated by alluvial plain landform in Shandong Province, China. The region is rich in coal resources and coal mining has formed a large number of subsidence areas. In view of the difficulty of surface water regulation and storage in plain area and the fact that coal mining subsidence area can provide effective storage capacity. The mode of combination of flood, waterlogging control and water resources regulation by using coal mining subsidence area in the basin is put forward. The advantages and disadvantages compared constructing plain reservoirs with using coal mining subsidence area as reservoirs is recognized. The effects of flood control and waterlogging control in coal mining subsidence areas from the scale of watershed and specific cases are analysed. From the perspective of flood and waterlogging control effect, in 2025 and 2035, coal mining subsidence area can reduce the flood of 5% frequency by 12.43% and 34.22% respectively. By 2025, urban waterlogging at 20% frequency will be reduced by 56.19%. In 2035, the ability of coal mining subsidence area to resist urban waterlogging at the same frequency can reach 100%. The coal subsidence area in Longguhu can reduce the flooding at 10%, 5% and 2% frequencies by 15.8%, 12.1% and 9.2%, respectively. It can completely resist the one-day waterlogging in the city at 20% frequency and reduce the waterlogging in the city for three-days by 70.8%. The reconstruction of plain reservoir using the coal mining subsidence area is feasible in technology and engineering construction. But it is still faced with the problem to be solved of the guarantee rate of water supply, water quality etc…

Abstract
In order to investigate the influence of the growth characteristics of onions in the Hexi Corridor, this paper tested the growth characteristics of onions in the Oasis by using the early golden dragon onion as a test material and randomly grouped it into different irrigation modes and cover methods. There were five treatments in the experiment, and the growth characteristics of onion was measured in each reproductive period, and the results showed that: The transverse diameter and longitudinal diameter of bulb showed a decreasing trend with the increase of regulation deficit range. The transverse diameter and longitudinal diameter of bulb in T3 treatment were significantly lower than those in T1 and T2 due to the large amplitude of regulation deficit in the whole growth. There was no significant difference between T1 and T4, but it was significantly larger than T5. Moderate deficit and fine sand mulching were not conducive to the growth of bulb transverse diameter and longitudinal diameter.According to the growth characteristics of onion, the best regulation of onion growth can be achieved by covering the whole growth period with black plastic film and sufficient irrigation, which has theoretical guidance and reference significance for onion planting in Hexi irrigation area.

Authors: Lv Jihong 
Published: February 2021

Abstract
Traditional airport location work mainly relies on 2D CAD drawing to draw and express the intersection relationship of multiple three-dimensional planes in space. In this way, the mapping speed and update are slow. And it involves more professional knowledge. It is difficult for non site professionals such as the planning department and the government to understand. They still use the method of manual on-site measurement points to calculate the excavation and filling volume, which makes the site selection work and earthwork volume calculation in the site selection stage time-consuming and laborious. In this paper, the airport model based on CAD design drawing and the three-dimensional real scene model of the site to be selected based on photogrammetry technology are established. The two-dimensional GIS analysis function and three-dimensional GIS visualization function of SuperMap are used to realize the high integration of two-dimensional data and three-dimensional GIS, and the three-dimensional real scene model of airport with superimposed design drawings is established, which is used for the evaluation and display of airport site selection.

Published: February 2021

Abstract
By using exhaust gas concentration tester, the degradation efficiency and mechanism of asphalt pavement coated with nano-TiO2 composite photocatalyst (TCP) has been analyzed. The results showed that the addition of dispersant greatly reduced the amount of TCP under the condition of similar degradation efficiency. When the optimum coating amount of TCP is 500g/m2, the degradation efficiency reaches 76.39%. As shown by scanning electron microscope, the TCP without dispersant will aggregate and exhibit uneven dispersion, while the TCP containing dispersant does not have this phenomenon, which indicates that TCP have a better exhaust gas degradation effect after being mixed with dispersant.

Published: February 2021

Abstract
Taking Georgia’s E60 Highway No. 3008 tunnel as the engineering background, a finite element calculation model was established for the construction stability of the shallow buried and unsymmetrical section of the tunnel exit, and the slope displacement and deformation and the construction dynamic characteristics of the supporting structure were analyzed. Finally, through analysis, the dangerous parts in the construction process are obtained. The analysis results show that: it is safe and feasible to simultaneously excavate the entrance section of the tunnel with unsymmetrical pressure and small spacing using the full-section method. The slope settlement process roughly goes through three stages: rapid change stage, slow change stage, stable stage, and the position stability of the slope toe is more sensitive to the overall construction of the tunnel. The maximum vertical settlement occurs at the position of the vault at the end of the tunnel, and more attention should be paid to this position during the construction. The research results can provide a certain theoretical reference for the construction of similar road tunnels in Europe.

Published: February 2021

Abstract
As urban land use is relatively tight, the rational use of sludge landfills has become a problem that must be solved. Because the sludge has the characteristics of high water content, poor permeability, strong flocculation, high combined water content, and high organic matter content, the traditional vacuum preloading method, stacking preloading method and other curing methods are too inefficient and can not meet engineering requirements. In this paper, an indoor electroosmosis drainage consolidation test was designed for sludge in a sludge landfill area in Shenzhen. The test results show that the reasonable drainage method, stacking method and shortening the electrode spacing increase the strength of solidified sludge by 1.1 times, 1.6 times and 2.8 times. The water content is reduced by 19.8%, 25.5% and 55.6%.The drainage rate is linear with the current.

Published: February 2021

Abstract
Combined with the construction of the No. 6 tunnel of the Khevi-Ubisa-Shorapani- Argveta section of Georgia’s E60 highway, the Midas GTSNX software was used to simulate the stability of the tunnel portal section during full-face construction. This paper analyzes the characteristics of displacement and stress variation of the tunnel portal slope during the whole section construction, the deformation law of surrounding rock during the whole section excavation, the deformation law of the initial support and final lining structure of the tunnel. The results based on the numerical simulation analysis show that when the entrance section of Georgia Tunnel No. 6 adopts full-face construction, the displacement of the supporting structure and the rock mass at the 5 m in front of the tunnel entrance changes greatly. Therefore, it is recommended to complete the invert construction of the tunnel before construction to ensure the safety of the tunnel entrance section; As for the entrance section as a whole, during the full-section construction process, the side slope of the entrance, the surrounding rock of the tunnel, and the supporting structure are all in a relatively stable state. Therefore, the full-section excavation of the No. 6 tunnel entrance section is safe and feasible.

Abstract
Modern Yellow River Delta has become one of the areas with serious land subsidence disaster in the plain area of Shandong Province. In this paper, Small Baseline Subsets - Interferometry Synthetic Aperture Radar (SBAS-InSAR) technology was used to process the Sentinel-1A data from August 2018 to October 2019 in the modern Yellow River Delta, in order to obtain the range and rate of land subsidence in the study area. At the same time, use the Leveling results of the same period to verify the accuracy. By selecting four larger land subsidence rate as feature points to analyze the characteristics of surface time series deformation, the influencing factors of land subsidence in this area are found out. The results show that during the past 2018-2019 years, the land subsidence in the the Yellow River Delta area was mainly distributed in Xianhe Town, southern the Huanghekou Town, Hubin Town, Guangrao County and its surrounding areas, DaWang Town, Yingli Town, Yangkou Town and the western part of Binhai Township, the most serious subsidence area is located in Xianhe Town, with an annual settlement rate of -204.7 mm/a. The land subsidence in the Yellow River Delta is mainly affected by groundwater overdraft, and the distribution characteristics of land subsidence funnel and deep groundwater depression funnel are basically consistent. In addition, natural factors such as consolidation of Quaternary loose sediments and regional tectonic movement also exacerbate the occurrence of land subsidence.

Published: February 2021

Abstract
Based on the environmental functional area allocation, point and non-point sources, hydrology and water quality data of Hun River, SWAT model is built and used to calculate the hydrological, water quality and environmental capacity processes in the river channel. The results showed: (1) When the upstream water quality concentration was limited to the grade III of the national surface water quality standard, the environmental capacity of total phosphorus (TP) in Hun River is about 582.01 t/a. (2) According to the results of water environmental capacity in different water periods, the environmental capacity of Hun River is seriously overloaded in the flood season, although annual value is satisfied the standard. For the strong driving effect on the pollutants transport in the river by the intense rainfall in flood season, the concentration in flood season exceeds the water quality standard of grade III. (3) To strengthen the environmental management of Hun River, it is necessary to monitor non-point sources in the cultivated land, standardize the fertilization measures, and improve the rural sewage pipe networks and related facilities.
Construction stability analysis of large section highway tunnel portal section based on numerical analysis
Authors: Wang Fuhua , Li Jun , Ding Libo , Wang Yetao , Song Zhanping 
Published: February 2021

Abstract
the entrance portal of No.8 tunnel of F3 bid section of E60 highway in Georgia is shallow buried and under unsymmetrical pressure, which leads to high risk and difficulty in tunnel construction. Tunnel 8 is designed based on ADECO-RS (analysis of controlled deformation in rock and soil). In order to understand the stability characteristics of tunnel portal in the whole section construction process and determine reasonable and feasible engineering countermeasures, the numerical simulation analysis of tunnel construction process is carried out. We not only studied the relationship between the stability of the slope at the entrance and the stability of the whole tunnel body under the actual stratum conditions, but also studied the mechanical and deformation characteristics of the surrounding rock and supporting structure of the tunnel.The numerical analysis results show that the stability characteristics of the portal slope directly affect the overall stability of the tunnel portal section; due to the disturbance of tunnel excavation, a large range of plastic zone appears at the interface of rock and soil at the portal section, resulting in large settlement deformation of vault. The collapse and deformation of the upper soil layer with poor engineering properties will cause excessive additional load on the supporting structure of the tunnel.Therefore, advance support measures should be taken to control the excessive deformation of vault. At the same time, due to the influence of asymmetric pressure, the supporting structure of the shallow buried side and the deep buried side of the tunnel appears obvious asymmetric pressure state. It is suggested to strengthen the stiffness of the shallow buried side support structure and adopt the asymmetric support structure to ensure the safety of the support structure.
