Published: November 2019

Abstract
In order to solve the problem of insufficient support strength caused by unreasonable structure design of roadway side retaining roadway along goaf in zhubai Coal Mine, and by means of preliminary test of bearing capacity, theoretical calculation and mechanical experiment of sand pillar, the optimization design of supporting structure of gob-side entry retaining was carried out. The results show that when the ratio of sand and stone material filled with sand column is 1:1 and the filling material is vibrated by adding water, the density of filling material reaches the maximum and the stability of sand column is optimal; When the pressure gauge reading is 32 MPa, the lower part of the sand column is in the basic fracture state and the watersand column can bear more ultimate load than the water-sand column. It is proved that the optimized sand pillar support body can meet the support strength requirements of gob-side entry retaining and improve the production efficiency.

Published: November 2019

Abstract
With the acceleration of urbanization in China, large-scale tunnel engineering has developed rapidly. The anti-seismic problem of tunnel engineering has become a research hotspot in the field of geotechnical seismic engineering. In this paper, the basic solution method of the orifice problem in the elastic theory is used to solve the internal force of the tunnel earthquake. The results show that the internal force of the tunnel structure is distributed along the circular tunnel in the shape of a goose egg. The larger the peak acceleration of the input seismic wave, the stronger the internal force of the tunnel structure. The conclusion provides a basis for anti-seismic design calculation of shield tunnel.

Case study on the model test of staggered-jointed assembling shield tunnel structure reinforced by bonded steel plates under large deformation
Authors: Liu Xue-zeng , Lai Hao-ran , Sang Yun-long 
Published: November 2019

Abstract
Transverse large deformation is one of the main diseases of metro shield tunnels, gravely threatening the safe operation of tunnel structure. Reinforcing bonded steel plates is a primary means for repairing excessively deformed tunnels. Nevertheless, evaluations and analyses on the reinforcing effect of bonded steel plates are currently unclear. Therefore, destruction tests were performed on the tunnel without the reinforced structure and on the excessively deformed tunnel with the reinforced structure respectively with the similar model test method in this paper, so as to analyse deformation behaviours and failure modes of segment lining and compare the reinforcing effect. Test results show that the carrying capacity of the tunnel structure can still be improved through reinforcing the staggered-jointed assembling shield tunnel with bonded steel plates under large deformation; also, the reinforcement of bonded steel plates can effectively prevent the tunnel from deforming. The failure mode of the reinforced structure consists of the reinforcement interface debonding failure and steel plate bending failure. To be specific, the debonding failure being frequently detecting in seams is composed of slab staggering and expansive debonding. Research achievements in this paper may provide theoretical and data support for similar reinforcement projects.

Abstract
In this study, the seismic responses of two kinds of optimized metallic energy dissipation devices (EDDs) are investigated by conducting shaking table tests on two storey full-scale steel frame model. The dampers are installed in pairs between the beams and corresponding cross bracings on each storey of the model. Then the whole setup, with and without dampers are subjected to different seismic waves with Peak Ground Accelerations (PGAs) of 0.14g, 0.40g, 0.62g and 0.90g with various configurations. In this paper, the dynamic properties, seismic responses and damage details of these distinct setups are recorded, analyzed and compared between controlled and uncontrolled structures. Thus obtained result shows that the effect of these kinds of dampers on acceleration and displacement are quite significant. This study lays down a firm foundation for the reliability of these kinds of passive energy dissipation devices on the basis of deeper research investigations.

Authors: Xu Ming , Song Zhanfeng , Zhang Wang , Yang Maomao , Ji Jing 
Published: November 2019

Abstract
This paper presents the mechanical performance of angle steel confined reactive powder concrete (ARRPC) short column under axial compression. A series of analysis were carried out on eleven specimens using RPC, batten plate spacing and slenderness ratio as parameters. The steel model the simplified bilinear constitutive model and RPC model was defined by the nonlinear constitutive model considering hoop effect, then the static simulation of ARRPC short column was carried out by ANSYS. The outcomes of analytical procedures mostly match well with the experimental results, so the rationality of the material constitutive model and the finite element model was verified. Based on this, the static behaviour analysis of eleven groups of ARRPC short column was carried out, and the load-displacement curves of the specimens were obtained. The effect of different parameters on the ultimate bearing capacity of the specimens was investigated. The numerical investigations show that when RPC strength is high, the specimens exhibit relatively large bearing capacity, while slenderness ratio and batten plate spacing increase, the ultimate bearing capacity of the specimen decreases. Finally, it can help propose the calculation formula of the bearing capacity of composite columns.

Authors: Pei Junjie , Fang Guangxiu 
Published: November 2019

Abstract
We made one of the new composite beam-column joint as tested specimen, and four specimens. By doing the model test under static load, we got some experimental results about specimens. For example, the cracking load, the ultimate bearing capacity, the load-deformation curves and the mechanical characteristic of the composite area of beam-column joint. We get conclusions as follow. The values of cracking load and ultimate bearing capacity of the new composite mixed using concrete and recycled concrete can be calculated by the formulas in Code for design of concrete structures (GB 50010-2010). As the structural style of the whole Cast-in-situ concrete specimen and the new composite mixed using concrete and recycled concrete is different, the law of the development of the deflection is similar, and we put forward modifier formula for calculating the bending rigidity. Adopting the structural with step-shaped composite area at the end of beam is useful for prevent cracks from running on, and the method can enhance its bearing capacity.

Published: November 2019

Abstract
In order to improve the comprehensive performance of the recycled concrete, reduce the waste of natural resources and environmental pollution, fly ash and recycled concrete aggregates were mixed into the reference concrete group RC0 to partially replace cement and natural coarse aggregates, respectively. The basic mechanical properties of five groups of recycled concrete reinforced with recycled fibers and organic fibers in different combinations were analyzed. In addition, the cracking resistance, failure process and bearing capacity of each group of recycled concrete beams were also studied. The test results and corresponding analysis showed that: the damage process of concrete beams reinforced with hybrid polyacrylonitrile fibers and recycled fibers was basically the same as that of ordinary concrete beams; the development of cracks is more effectively prevented with the increase of the proportion of waste fibers; the use of recycled waste fibers and polyacrylonitrile can significantly improve cracking resistance, deformation resistance, and load carrying capacity of recycled concrete beams.

Published: November 2019

Abstract
The shear strength and the failure deviatoric stress of the Wuhu soft soil under different confining pressures were determined by indoor undrained consolidation triaxial rheological tests. Selecting 20%, 40%, 60% and 80% of the failure deviatoric stress as deviatoric stress and 100kPa, 200kPa and 300kPa as confining pressures, the rheological tests were conducted by separate loading method. Based on the creep curves obtained from the rheological tests, the related model parameters were determined after modifying the stressstrain and strain-time relation of Singh-Mitchell and Mesri creep model. And the empirical creep model was obtained, of which the stress-strain and strain-time relation were expressed in the form of power function. The analysis indicated that the creep characteristics of Wuhu soft soil was described more accurately by the new empirical creep model than Singh-Mitchell and Mesri creep model.

Authors: Wang Qin , Liu Yong , Zhang Xiangping , Yaquan Ba 
Published: November 2019

Abstract
To optimize the existing flood control plan of Aksu River basin and strengthen the flood control management during the flood season, the flood routing of Aksu River is studied based on the improved Muskingum method. Firstly, to make up for the shortcomings of the traditional Muskingum method in flood routing of double tributaries, the parameters of single tributary are further improved. Then, the improved Muskingum method is used to simulate and validate the flood process of Shaliguilanke, Xiehela and Xidaqiao hydrometric stations in Aksu River from 1999 to 2016. The results show that: (a) In the main stream of Aksu River, the flood of Xidaqiao Hydrometric Station is mainly caused by the water coming from Xiehela Hydrometric Station, while the flood caused by the water coming from Shaliguilanke Hydrometric Station and two stations (Shaliguilanke Hydrometric Station and Xiehela Hydrometric Station) is less. (b) We classified the main streams of the above three situations by flood peak level, and then carried out flood routing. The calculating parameters under the same flood peak level all show strong integrity, and the fitting degree between the simulated process and the observed process is relatively high. The parameters K and x inversely deduced under the condition of the inflow of Xiehela Station as the main source have more physical significance.

Authors: Xu Tianyi , Liu Keqiang 
Published: November 2019

Abstract
Southern Jiangsu Province in Taihu Basin is one of the regions with high urbanization degree in China. In recent years, with the continuous progress of urbanization, the human activities, have further increase the pressure of flood disasters. This paper analyzed the trends of most significant human activities, namely the land use pattern, surface water storage capacity, and construction of polder areas and urban flood control projects; simulated the water yield and water level of regional river network by using a digital watershed model. The results indicated that in the past decades, the construction land expanded significantly, the capacity of flood storage decreased gradually, and the drainage module increased by large-scale construction of polder areas and urban flood control projects. The change of these factors would lead to the increase of the regional water yield and rise of flood level of river network, which would further increase the flood risk of the region.
