摘要

随着城市地铁建设的快速发展,地铁列车运行引起的环境振动问题已引起社会各界的广泛关注。以软件ABAQUS为计算平台,建立了隧道-地基动力相互作用分析模型,给出了模拟地铁列车振动荷载的表达式。以南京地铁沿线典型场地条件为研究对象,采用修正Martin-Seed-Davidenkov动粘弹塑性本构模型描述土的动力特性,分析了地铁列车运行引起的地表振动特性,给出了地铁隧道断面几何形式、隧道埋深、两平行区间隧道间的净距和场地条件等因素对地表振动特性的影响规律,为地铁选线和地铁邻近建(构)筑物的减、隔振设计提供参考依据。
With rapid development of urban subway construction, environmental vibration problem induced by passing trains in subway tunnel has attracted broad attentions of the society.Based on ABAQUS finite-element software,the soil dynamic viscoelastoplastic constitutive model based on modified Martin-Seed-Davidenkov model is used to describe the dynamic character of the soils.The equation describing the vibration load induced by the passing trains in subway tunnel and the model of the tunnel-soil interaction analysis are built.The characters of ground vibration induced by passing trains in subway tunnel are analyzed.Different influence factors on the characters of ground vibration are also considered in the paper.The results can provide some basic data for the line choice of subway tunnel and mitigation of environment vibration
