一、前言 粘性土的地震上压力是一个比较复杂的研究课题,目前在国内外尚未取得完满的结果。为了工程实际的需要,许多学者曾提出一些实用的静力计算方法。归纳这些方法大致可分为两大类:一是不考虑内摩擦角(即ψ=0)的粘性土计算方法,有如日本抗震设计标准中所推荐的方法等;另一是考虑ψ的粘性土计算方法,有如图解法、简化法等。 本文建议的粘性土地震土压力计算方法是以库仑土压力理论为基础,将地震时墙后破
I. INTRODUCTION Earthquake pressure on cohesive soils is a relatively complex research topic and has not yet achieved satisfactory results at home and abroad. For the practical needs of engineering, many scholars have proposed some practical methods of static calculation. To sum up, these methods can be roughly divided into two categories: First, the calculation methods for cohesive soils without considering the internal friction angle (ie, ψ = 0) are similar to those recommended in Japan’s seismic design standards; the other is to consider the cohesive soil The calculation methods include graph solutions and simplified methods. The seismic earth pressure calculation method for cohesive soils proposed in this paper is based on the theory of Coulomb earth pressure and will break the wall when the earthquake occurs.
