近距离平行隧道和交叠隧道中轨道列车同时运行引起的环境振动明显高于单列车运行情形，对此类环境振动进行定量计算和预测是一个亟待解决的问题。以苏州轨道交通4号线为背景，建立近距离平行隧道-地基平面有限元模型，研究在不同列车荷载组合、不同隧道间距及不同隧道埋深下的地面振动响应特点和规律，并对数值计算结果进行多项式拟合，得到基于双列车荷载作用下的地面振动预测公式，为工程设计和环境评价提供参考。
Abstract
The environmental vibration caused by the simultaneous operation of rail trains in overlapping or close tunnels is higher than that under a single train load.Its quantitative calculation and forecasting is an urgent problem to be solved.A finite element model for analysing the close parallel tunnel-ground structure based on Suzhou Rail Transit Line 4 was established to study its ground vibration responses.The characteristics of ground vibration responses were studied under different train loads combinations,different depth and distance between the two tunnels.The numerical simulation results were processed by using polynomial fitting to get an empirical formula under double train loads.The results can provide references to engineering design and environmental assessment in future.
