摘要

对地震土压力的研究是地震区挡土墙安全设计的一项重要课题。地震条件下

目前的研究主要是给出了土压力的近似拟静力解析解。本文采用可考虑动力荷载下的周期和纵波及横波效应的拟动力方法

对挡土墙后的地震被动土压力进行分析。在挡土墙后平面滑裂面假设的基础上

考虑了水平和垂直向地震加速度、纵波速度、横波速度、挡土墙摩擦角、填土内摩擦角、填土坡角对地震被动土压力的影响。与Mononobe-Okabe理论的拟静力法不同的是

用本方法得出了沿墙身地震被动土压力是非线性变化的结果

这更符合地震条件下土压力的变化规律。

Abstract

Estimation of the seismic earth pressure is an important topic of research for the safe design of retaining wall in the seismic zone.But under seismic condition

the available solution mostly give the pseudo-static analytical value of the earth pressures as an approximate solution to the real dynamic nature of the complex problem.A recently developed pseudo-dynamic method

which incorporates time dependent effect of applied earthquake load and effect of shear and primary waves

is applied to study the seismic passive earth pressure behind a vertical retaining wall.A planar failure surface has been considered behind the retaining wall

the effects of horizontal and vertical earthquake accelerations

shear wave velocity

primary wave velocity

wall friction angle

soil friction angle

the ground slope of backfill on the seismic passive earth pressures has been explored.Unlike the Mononobe-Okabe method

which is pseudo-static analysis

the present analysis predicts a nonlinear variation of passive earth pressure along the wall

which is more realistic under earthquake condition.
