摘要/Abstract

摘要： 为了研究水平-摇摆耦合激振作用下层状和竖向非均匀地基波阻板（简称WIB）的三维隔振效果，基于薄层法研究层状介质中波传播问题的高效性和边界元法处理无限域问题的精确性，建立了以薄层法基本解答为格林函数的半解析边界元法。分别对上软下硬和上硬下软层状和竖向非均匀地基中WIB的三维隔振效果进行了分析。研究表明，地基的分层参数和非均匀性对WIB的隔振效果有显著影响，上硬下软地基的隔振效果稍好于上软下硬的情况。

Abstract: In order to study the three-dimensional (3D) isolation vibration effectiveness of wave impeding block (WIB) in layered and vertical heterogeneous foundation under horizontal-rocking coupled excitation, a 3D semi-analytical boundary element method (BEM) model based on thin-layered method (TLM) efficiently to study the wave propagation in layered ground and BEM precisely to solve infinite domain problems is presented. The analysis is accomplished with this model, on which the Green’s function is regarded as fundamental solution of a stratified half-space. Then the active isolation effectiveness of WIB is studied in layered and vertical heterogeneous foundation. The results show that the stratification parameter and the heterogeneity have significant influence on the vibration isolation effect of WIB, and the isolation vibration effectiveness of the upper stiff-layer and lower soft-layer ground is better than it of the upper soft-layer and lower stiff-layer ground.

Key words: wave impeding block, thin-layered method, boundary elements, horizontal-rocking coupled loading
