摘要
运用薄层单元法与有限单元法结合的方法,对地铁列车运行时的地面振动进行了分析研究,计算了离地铁隧道不同距离的地面加速度,并与实测结果进行比较,结果吻合较好,可为地铁运营时对周围环境的振动影响提供预测与参考.
In this paper,ground vibrations due to underground railways were studied by the coupling the thin layer element(TLE) method and the finite element(FE) method.The ground accelerations with different distances from tunnel were calculated.The results are correspond with the measured.It is shown that the model can provide a reference for predicting environmental vibration.
