摘要:

针对饱和地基上列车运行引起的地面振动问题,利用列车-轨道有限元模型计算得到轨道与路基间的相互作用力,经傅立叶变换后作为地面振动计算的激励荷载;在此基础上,结合由薄层法得到的饱和地基动力Green函数,时饱和地基上列车行驶条件下所产生的地面振动进行了计算分析和振动评价.结果表明:列车车速在一定范围内对振动有较大影响;列车引起的地面振动在近轨道处基本能够满足住宅区振动标准.

Abstract:

Aiming at the ground vibration problem caused by train operation on saturated foundation, the interaction force between track and roadbed is calculated by using the train-track finite element model, and the excitation load is calculated by ground vibration after Fourier transformation. On this basis, combined with the saturated foundation dynamic Green function obtained by the thin layer method, the ground vibration generated under the traveling conditions of the train on the saturated foundation was calculated and evaluated. The results show that the train speed has a great influence on the vibration within a certain range. The ground vibration caused by the train can basically meet the vibration standard of residential areas at the near track.
