摘要

基于轮轨相互作用原理，建立了城轨交通高架线路列车振动荷载激励函数。将该激励力作用在有限元软件建立的三维轨道支承结构和土体传播路径计算模型上，对地铁运行引起的周边环境振动响应进行了仿真模拟，并利用现场实测数据进行了比较和验证。进一步，分析了列车运行速度和场地土特性对环境振动的参数影响。在对各参数的影响特征进行了定量分析的基础上，通过统计分析，建立了城市轨道交通高架线路环境振动的振级预测公式，并利用现场实测数据进行了验证。研究表明，仿真模拟和预测结果能够较为真实的反映城轨交通高架线路运行引起的环境振动的实际情况。

Abstract

Firstly

on the basis of wheel-track interaction theory

a function of exciting force of moving train on elevated line is established. Then

the exciting force is acted on the three-dimensional numerical models of rail structure

elevated line and soil foundation by utilizing the finite element software. The surrounding environment vibration response caused by train operation is simulated; and the numerical results are compared and verified by the field measurement data. Furthermore

the parameter effects of length of bridge span

train speed and soil properties on environment vibration are studied. On the basis of investigation of parameter influence characters and according to the statistical analysis

a prediction formula of vibration level on ground induced by urban rail transit with elevated line is presented and validated by the field experiments. The research results show that the numerical simulation and prediction can truly reflect the actual environment vibration caused by urban rail transit with elevated line.
