| 摘 要： | 基于上下限原理的推论,分析不连续速度边界下土体中不连续应力场和不连续速度场。根据应力不连续线和速度不连续的性质,在考虑有重土,土体和墙体摩擦情况下,通过数值计算,解三类边值问题,求得不连续速度边界下挡土墙墙后土体中的静力场。同时对对应的机动场进行分析,找出了满足速度边界条件的静力场,解得不连续速度边界下挡土墙土压力的严密解。计算结果表明:当不考虑土重、土与墙体之间的摩擦时,结果与前人成果一致。

| Abstract: | According to the characters of the discontinuous stress and velocity lines,the stress fields and the corresponding velocity fields are analyzed through the numerical calculation based on the deduction of the upper and lower bound theorems.Three kinds of boundary conditions are solved.The weight of soil and the friction between the retaining wall and soil are taken into account.The stress fields satisfied with all velocity boundaries is found.The rigorous solution of the earth pressure under discontinuous ve... |
