Published: May 2020

Abstract
Mechanical deformation of buried pipeline under vertical load is the result of pipe-soil interaction. In order to reveal the necessity of pipe-soil interaction while investigating mechanical properties of buried pipeline, the ANSYS commercial software is employed to construct pipe-soil interface and simulate pipe-soil coupling effect. With the newly developed model, mechanical properties of pipe under vertical static load are analyzed. Numerical solution is subsequently compared with analytical solution. The results reveal that (1) There is maximum Von Mises stress at internal surface of pipe side under overlying load, and minimum Von Mises stress appears in the pipe shoulder at angle of about 45°to x-axis; (2) The pipe-soil interaction has significant effect on analyzing the deformation and distribution of stress of buried pipeline; (3) Vertical displacement obtained from Marston model is larger than that obtained from newly constructed numerical model; (4) The deformation of pipe is obviously constrained by backfilled earth around the pipe. For a buried pipe, especially the elastic pipe, it is necessary to consider pipe-soil interaction while analyzing its mechanical properties.

Research on Distribution Network Loss Allocation with Small Hydropower Groups
Authors: Liu Jiajun , Yang Xiaoqian 
Published: May 2020

Abstract
On the basis of Longnan power grid with small hydropower groups, this paper proposes a loss allocation method combining marginal loss coefficient method and branch dissipation power transfer component method, aiming at the fact that marginal loss coefficient method does not consider the influence of balancing nodes and different balancing nodes on allocation results. Firstly, starting from the circuit law, Norton’s equivalent is used to equivalent all power supplies to node injection current. Based on the branch dissipation power transfer component method, the network losses that each power supply node including the balancing node should share are obtained. Then, the marginal network loss coefficient method is used to obtain the network losses shared by other nodes except the balancing node. Finally, the calculation and analysis of the Longnan power grid with small hydropower are carried out, which verifies the feasibility of the proposed method and has reference value for the distribution of network losses of other distributed power grids.

Published: May 2020

Abstract
Reservoir leakage is typically a potential risk to reservoir operation in the world. However, due to the difference of climate, hydrology and geology conditions, the patterns and causes of water leakage in different reservoirs are quite different. This study took the Tai’an pumped storage power station reservoir in Shandong Province as an example to analyze the H-O isotope characteristics of various waters in detail. The results showed that the δ18O, δ17O and δ2H values in the reservoir water collected in July were significantly more positive than those in September and October, and other waters also had similar variations. The isotopic difference between September and October was not significant. Isotope analyses showed that water leakage varied with months: in October, well water and leakage water in the right bank gallery and bottom gallery drainage hole 005 did not come from the reservoir, while other waters were closely related to the leakage of reservoir water; in September, well water in the left bank did not originate from reservoir water leakage, while water in the measuring weir behind dam and the right bank gallery drainage hole were closely related to the reservoir water. In July, leakage water in the right bank gallery drainage hole and reservoir water had a close relationship. Our findings are expected to be helpful for guiding the treatment and control of reservoir water leakage.

Authors: Guo Zhangjun , Huang Huadong 
Published: May 2020

Abstract
The high-performance concrete dam deformation prediction model serves as an important reference for structural safety behavior diagnosis, early warning, and scientific decision-making, and it is also one of the guarantee measures to fully exert the benefits of the project. This paper aims at the subjectivity of factor selection, multicollinearity among factors, and poor generalization of the concrete dam deformation monitoring model. It combines rough set and random forest theory to achieve feature attribute reduction, importance evaluation, and high-precision prediction. In terms of rough set and random forest advantages, a concrete dam deformation prediction model based on RS-RF was established. The application of engineering examples shows that the deformation monitoring model of concrete dams based on RS-RF can reduce the influence factor set, give the importance of each factor, and do well than commonly used models based on SVM and RF in prediction accuracy. Therefore, the deformation prediction model of concrete dam based on RS-RF achieves optimization of influence factors, which makes up for the shortcomings of intelligent prediction model in quantitative analysis and prediction generalization, and has strong engineering practicability.

Published: May 2020

Abstract
Three group model tests are designed to study the change law of lateral bearing behavior at different scour depths and the local scour is simulated by changing dimensions of scour hole. The favorable effect of remaining sand above the scour depth line is considered to get the calculation method of equivalent depth. Simulation was carried out using LPILE and the results were compared with those obtained from model tests. The results show that the equivalent scour depth formula derived based on the principle of invariable ultimate soil resistance is reliable, and the relative error between the LPILE calculated value and the test value is 13-17%, which indicates that the actual situation can be accurately predicted. The sensitivity of the scour depth, scour slope angle, and scour width parameters were analyzed to determine their effects on the scour hole and the validity of the theoretical equation; the results show that the impact of the three parameters decreased in turn, which can provide some reference for engineering design.

Abstract
Numerical simulation analysis was conducted on the shield tunneling construction of the right line between Tangdong station and Huangcun station of Guangzhou rail transit line 21, the right line subway shield underpassing the underground pedestrian passage at close range. The numerical simulation vertical settlement of the ground and floor outside the foundation pit was compared with the field monitoring. The results show that the numerical analysis of the trend of land subsidence is consistent with the field monitoring, the thickness of the tunnel roof overburden has a great influence on the ground settlement. The ground settlement is mainly subsidence with thick overburden, while the thin overburden, the ground settlement is mainly uplift; the Equivalent Circular Zone formed by simultaneous grouting and secondary grouting has a great influence on the ground settlement. During the site construction, the tunneling parameters should be adjusted according to the site monitoring, and parameters such as soil and water pressure on the tunneling surface, overburden thickness, synchronous grouting pressure and secondary grouting pressure should be taken into comprehensive consideration to control the tunneling of shield underpassing the existing structures at close range.

Authors: Wei Cunhou , Wen Nie , Liu Qiang 
Published: May 2020

Abstract
Study on powder behavior is the key to dust pollution prevention and control in tunnel construction environment, using wind energy to control dust diffusion is a common and effective dust control method at present. In this paper, the numerical simulation and field measurement were used to study the powder diffusion in construction of a tunnel boring machine (TBM)-based tunnel, in which the movement and diffusion properties of the powder in the tunnel were achieved and analyzed. By adjusting the height of the exhaust vent and the secondary blowing distance (LP), the quality of air in the tunnel was optimized. The accuracy of the simulation results was also verified by the field measurements. The results showed that when the height of the dusty return airflow (HW) is close to that of the exhaust vent (HE), the rock-dust concentration in the tunnel could be reduced to a certain extent. When LP < 50 m, the primary and secondary blowing airflows could form a coupled wind field in the middle of the tunnel to limit the further backward diffusion of the rock-dust. When LP > 50 m, the dust-control air-curtain could be formed within 18.83 m away from the heading. When LP = 60 m, the rock-dust in the tunnel was effectively controlled, and the diffusion distance of the rock-dust was less than 16.4m as well.

Published: May 2020

Abstract
Four kinds of organic polymer emulsions of silicone acrylic, styrene-acrylic, waterborne epoxy and acrylic acid were selected and mixed into cement paste according to different poly-ash ratio, and experimental studies on their physical properties (fluidity and water-absorption rate) and mechanical properties (compressive strength, bending strength and bend-press ratio) were carried out. The results show that in terms of physical properties, only the waterborne epoxy emulsion improves the fluidity of the material, the four organic polymer emulsions reduce the water-absorption rate of the material, and the water-absorption rate of waterborne epoxy emulsion and styrene-acrylic emulsion decreases respectively by 61.8% and 51.5% at a poly-ash ratio of 0.15. In terms of mechanical properties, the four organic polymer emulsions fail to improve the compressive strength of the material, but the toughness of the material is improved. The waterborne epoxy emulsion has a 16.7% improvement in the bending strength at a poly-ash ratio of 0.2, and the styrene-acrylic emulsion has a 9.7% improvement in the bending strength at a poly-ash ratio of 0.15.
Analysis of the impact of rock hardness on the seismic response characteristics of CAP1400 nuclear island structure
Authors: Li Furong , Long Hui , Chen Guoxing 
Published: May 2020

Abstract
With the rapid development of the nuclear power industry, appropriate sites for nuclear power plants have become a scarce resource. The construction of a nuclear power plant is subject to stringent requirements of site selection, and it is necessary to ensure that the plant will have sufficient seismic resistance. In this study, targeting the CAP1400 nuclear island structure as the research object, a three-dimensional finite element model of the dynamic interaction between the nuclear island structure and the foundation is established by considering the nonlinear characteristics of rocks using ABAQUS software. Our objective is to analyse the impact of rock hardness on the acceleration, displacement and floor response spectrum of the nuclear island structure caused by earthquake based on a total of 4 types of rock foundations with different degrees of hardness. The results show that, with the increase of rock hardness, the acceleration of the nuclear island structure increases, the displacement decreases, while the peak of floor response spectrum increases and moves towards the short period (high frequency band) direction. The seismic response of the nuclear island structure increases with the increase of elevation, and the greatest level of response is observed at the cooling water tank of the shield building, which therefore should be targeted as the key for seismic design. For rock foundations with high hardness, the seismic design for the nuclear island structure can follow the standard for rigid foundations so as to ignore the effect of the soil-structure dynamic interaction.
