多孔地铁隧道交叠运行环境振动影响数值分析
Numerical Analysis of Environmental Vibration Induced by Stacked Subway Tunnels Operation
摘要
Abstract
With the rapid development of subway construction, the distribution of subway tunnels is becoming more and more complex, such as parallel tunnels with close intervals, stacked tunnels and crossing tunnels. These subways can induce serious environment vibration. In this paper, 3D stacked tunnel models with different train operation conditions were built. The numerical calculation results were found to be in good agreement with those from the empirical formulae provided in some standards. On this basis, the influence of the number of the tunnel, the spatial positions of the tunnel and different train operation conditions on the environmental vibration was analyzed systematically. The simulation results show that the upper tunnel has a great influence on the propagation rules of the ground vibration induced by the lower tunnel in the train operation condition, and has a shelter effect to the near-field ground surface vibration of the tunnel. The horizontal spacing between the tunnels has greater influence than the vertical spacing between the tunnels. Different train operation combination has different effect on the ground vibration. These conclusions have provided some references for the assessment of subway environment vibration and subway design.关键词
