Numerical Analysis of Seepage Field Characteristics for Tunnel Engineering at Shaoquan Lake by WANG Hao, LIU Guang, WANG Jingfeng, ZHANG Xingqi, PU Yubing, YAN Zhong, DING Zhaodong

“…Waterproofing of the urban under-lake tunnels is directly related to the operation safety of tunnel projects.In order to analyze the waterproof performance of the tunnel,this paper establishes a three-dimensional numerical model of the tunnel under the lake based on the real tunnel structure,simulates the seepage state of the tunnel under different water depths and soil thickness through FLAC3D,and obtains the pore water pressure cloud map of the tunnel under different conditions.It is found that the maximum pore water pressure occurs at the top and outside of the tunnel,so improving anti-seepage measures shall be taken at these areas.After comparison of the anti-seepage performance of the concrete with different impermeable layer thickness by the numerical method,the results show that the anti-seepage performance of the concrete will be significantly enhanced with the increase of impermeable layer thickness.…”

Performance Analysis of Cognitive Radio System Based on Outage Probability of Cognitive Transmission by Haomin Gao, Haifeng Zhao, Xiao Liang, Xiaomin Mu

“…It is an important part to design an optimal spectrum sensing and transmission framework in cognitive radio network.Considering that cognitive data transmission outage had effect on the performance of cognitive radio system,a novel spectrum sensing and transmission model based on the outage probability of cognitive transmission was proposed and the two phases of spectrum sensing and data transmission were jointly optimized.The model was formulated as a nonconvex optimization problem under the constraint of interference to primary user,which maximized the average achievable throughput by the joint optimization of sensing time and data transmission rate and simulated by means of the numerical method.The numerical analysis shows that a better tradeoff can be achieved among the protection of primary user,the throughput of cognitive system and transmission delay when the outage probability is cited and the constraint is satisfied.…”
