摘要

基于动力学基本方程，运用有限单元法（FEM）和Newmark隐式积分方法，对隔震沟对车辆荷载（FWD荷载）引起的地基振动的隔震效率的影响因素进行了弹塑性数值分析。考虑到人工边界上波反射对计算结果的影响，分别用有限单元和半无限单元离散计算区域内部和边界，分析中主要考虑了隔震沟的位置、深度、宽度三个主要影响因素，基于计算结果总结出其影响规律。

Abstract

According to the basic equation of dynamics

using FEM and NEWMARK implicit integration algorithm

an elastoplastic numerical analysis is made to analyze the efficiency of vibration isolating groove to the vibration caused by vehicle load. In order to reduce the effect of wave reflecting on border

finite element and semi-infinite element are respectively used to discrete the internal and border parts. The position of the vibration isolating groove and its depth and width are the three mainly considered factors. Finally

on the basis of the numerical calculation results

their effect laws are analyzed.
