摘要

在非地震主动土压力公式的基础上，用微分薄层法给出了地震条件下主动土压力公式，其中填土面倾斜、墙背倾斜、填土为黏性土、墙背与填土间同时存在凝聚力c和内摩擦角? 作用、墙后破裂体存在水平向和竖向的地震加速度，目前所见的地震情况下和非地震情况下的主动土压力均是此公式的特例。对上述同一条件下的挡墙用过墙踵的整块破裂体作静力平衡分析（如库仑分析），得到的总土压力与文中微分薄层法得到的总土压力大小相等，但微分薄层法作用点位置明显增加，研究表明：设计抗震和非抗震各类挡墙时要引起足够的重视。

Abstract

On the foundation of non-seismic active earth pressure theory

the seismic active earth pressure formulas

in the conditions of filling surface incline

wall back incline

filling soil having the characteristic of c and ?

having the c and ? action between the wall back and filling soil

the filling soil having horizontal and vertical acceleration

were obtained with differential layer method

these formulas included their distribution and total force. At the present time

the every active earth pressure formula in earthquake and non-earthquake condition is the special example of this paper’s construction. The total earth pressure calculated with differential layer method is consistent with other method such as Coulomb’s earth wedge equilibrium method; but its acting position is raised up; therefore

the design of retaining wall oughted to pay enough attention to this aspect.
