Published: July 2020

Abstract
To promote the standardization and assembly of temporary roads for construction, according to the investigation and research, combined with the requirements of the code, from the perspective of bearing capacity and economy, a standardized construction temporary road scheme was proposed. The load and temperature stresses of assembled panels of different sizes were analyzed using the elastic ground plate theory. The load stress is significantly affected by the axle load of vehicle, and the temperature stress is significantly affected by the plate length. Plate length should not exceed 4m. The numerical analysis method was adopted and the joints were optimized. The tenon could effectively transfer the load. While the length of the tenon is 4cm, the load transfer effect is the best.

Published: July 2020

Abstract
Many safety issues can arise during the long operation time of dams because of various internal and external factors, among which dam leakage problems happen frequently. Dam leakage not only affects the normal functions of a dam, such as power generation, water supply, and irrigation, but also weakens the flood control ability of the structure and increases the risk of dam failure. According to the existing problems in concrete face rockfill dam(CFRD) leakage detection, an integrated leakage detection technology is proposed in this paper. The proposed technology can analyze the dam safety monitoring data and then combine the high-precision sonar and underwater robot detection to provide solutions for dam leakage problems.

Authors: Wang Chenchen , Xu Hongjun , Zhang Jindong 
Published: July 2020

Abstract
Due to the randomness of ground motion and the variation of the material itself, it is unreasonable to regard the inter-layer target displacement angle of the structure as a certain amount in the direct displacement-based seismic design. In this paper, an improved displacement seismic design method is proposed, which is characterized by: (1)Considering the reliability when determining the target displacement angle between layers, and combining the probability characteristics of the target displacement angle between layers, the seismic design of the structure has a certain probability meaning.(2)According to the quantitative relationship between damage index and displacement ductility, combining structural damage performance target, the displacement ductility of the structure is determined by the damage index in the displacement-based design method, and the determination of displacement ductility is directly related to the damage performance target. Finally, it is applied to the design of prestressed precast concrete frame structure, then OpenSees modeling is used to verify the improved displacement design method, and at the same time compared with the original design method. The results show that the improved displacement seismic design method proposed in this paper can well control the elastoplastic response of the structure and meet the performance of the structure. The original displacement design method is more conservative than the improved displacement seismic design method.

Abstract
Based on the investigation data of Jiaozhou Bay in May and October of 1979, the content and distribution of salinity in bottom layer in Jiaozhou Bay were studied. The results showed that in May and October, the variation range of salinity in Jiaozhou Bay water was 31.09-31.55 %o, and the salinity of sea water was over 31.09 %o. This showed that in the aspect of salinity change, in May and October, in the whole bottom layer of Jiaozhou Bay, the salinity of water body was relatively high. In May, in the bottom, the variation range of salinity in Jiaozhou Bay was 31.49-31.55 %o, and the salinity of sea water was relatively high. There was a low salinity area in the bottom of Jiaozhou Bay mouth. In the inner and outer waters of the bay mouth, the salinity was higher. The results showed that the salinity in Jiaozhou Bay was high and the salinity of the water outside the bay was high. In October, in the bottom layer, the variation range of salinity in Jiaozhou Bay was 31.09-31.21 %o, and the salinity of sea water was relatively low. There was a low salinity area in the bottom water outside the mouth of Jiaozhou Bay. Compared with the bay mouth and the water inside the bay mouth, the salinity of the water outside the bay mouth was relatively low, and the interval length of salinity change was 0.12 %o, and the salinity change from the outside of the bay mouth to the inside of the bay mouth was relatively small. In May, a low salinity area appeared in the bottom of Jiaozhou Bay mouth. In the inner and outer waters, the salinity was higher. In October, a series of decreasing parallel lines with different gradients were formed from the bottom high salinity water area in the inner side of the bay mouth to the bottom low salinity water area in the outerside of the bay mouth.

Authors: Wang Zhenlong , Lei Ming , Zhu Mei , Zhu Lingling , Wang Yining 
Published: July 2020

AbstractWinter wheat which was a typical dry crop in the Huaibei Plain was studied in the paper through the Wudaogou Hydrology and Water Resources Experimental Station, the long sequence of the lysimeter and the uninterrupted special experimental data. The multilevel water table depth was controlled from 0-5m in the experiments. By modeling the crop-water production function (Jensen Model), the tendency and regularity of the moisture sensitivity index variations of winter wheat cultivated was investigated under the above conditions at different plant developmental stages. The results showed that water deficits have greatly impacted winter wheat yield during key reproductive and seed formation periods, which are in the context of this analysis, the heading - maturation stage. Returning to green - jointing periods, the range of sensitivity to water deficits is 46.1% to 61.3%, which is the period towards maturation and 8.5% - 15.3% for the tillering period and overwintering period in maximum. The water sensitivity indexes reaches the maximum at the 1.0m ground water depth in the Shajiang black soil and Yellow fluvo-acquatic soil, which yields a 1.58 - 2.45 times and 1.16 - 2.08 times increase compared to the minimum in the same growth period. The groundwater depth should therefore be maintained between 0.8m and 1.2m in Shajiang black soil and Yellow fluvo-acquic soil. In comparison to other groundwater depths, this can reduce artificial irrigation and the occurrence of either waterlogging events or requisite drainage measures. Therefore, the findings of this study can optimize irrigation and improve water use efficiency.

Published: July 2020

Abstract
According to the profitability evolution of real estate development projects, it is necessary and meaningful to conduct an analysis of the development mode of the real estate using some quantitative and empirical methods. To achieve this goal, a full-cycle index model (FCIM) of real estate development and construction investment is used to generate a series of data at first, which includes 40 samples (key factors) with their internal rate of return (IRR) of what as the output and 38 influencing factors as the input. In addition, three strategies (i.e., correlation, representativeness of dimensions and bottom of factors) are applied to filter the sample data and thus getting 10 key influencing factors of the IRR. Then, a regression model that treats IRR as the output and key influencing factors as the input is constructed to determine the weights of these factors. Finally, multiple combinations of factors with higher weights are considered to lead to the innovation basis for the real estate development mode. In conclusion, three factors have the strongest impacts on IRR: land transfer fee, sales promotion, and stamp tax and three development modes referring to different real estate enterprises are summarized, which are L&H Mode, L&P Mode, and H&B Mode.

Authors: Wang Jinxi , Zhang Binwei , Yang Yang 
Published: July 2020

Abstract
To explore the vertical bearing capacity of pile foundations in the loess area, relying on the new construction project, a single pile vertical compressive bearing capacity field test was conducted on three test piles, and the Q-S curve and S-lgt curve of the single pile vertical static load test The analysis and research showed that the axial force of the three test piles had not been transmitted to the pile end, and the load was mainly borne by the reaction force provided by the frictional resistance of the pile side. The distribution of the axial force of the pile with depth is not only related to the size of the pile top load, but the nature of the soil around the pile is related to the typical friction pile characteristics, and the Q-S curves all show a slow-change type with no obvious steep drop. When loading 4900kN, none of them reached the ultimate failure, and the settlements of the three trial-installed piles were 12.24, 15.44 and 18.64mm, respectively. By comparing the test results with the design requirements, the bearing capacity of the single pile meets the requirements, indicating that in the loess area, the single pile has a higher bearing capacity, and the settlement is more uniform and the settlement is small, which can be used as a building foundation to bear a larger load.

Published: July 2020

Abstract
In order to investigate the stability of a derrick under wind load, a floor type double flat arm derrick is selected as the object, and the numerical simulation method is applied for the eigenvalue buckling analysis and the nonlinear stability analysis to get the instability mode and the critical wind speed in static stability. The results show that the position where the derrick first buckles is the connection between the derrick and the flat arm, and finally the torsional instability leads to the overall instability. The instability of the derrick without waist ring is caused by the damage of the main material of the tower leg. The mean wind speed in static instability is 56 m/s.

Abstract
Moisture content is a very important parameter in earthwork filling. In the process of earthwork compaction, the moisture content of the compacted soil shall be measured in time, and the moisture content shall be compared with the design requirements to check whether it is qualified. However, the conventional drying method usually takes about 6 to 8 hours, which will have a great impact on the construction progress. Therefore, this paper mainly discusses the alcohol combustion method in the construction site to temporarily replace the drying method to determine the moisture content of soil. The optimum sampling quantity, combustion times and the range of moisture content of alcohol combustion method are obtained. Finally, it shows the accuracy of alcohol combustion method in the temporary determination of soil moisture content in the construction site.
