不连续边界形状下土压力的严密解法

分析不连续边界形状下土体中不连续应力场和速度场特征，根据应力不连续线和速度不连续的性质，在考虑有重土、土和墙体摩擦情况下，同时利用上、下限定理，构建算法；通过数值计算解三类边值问题，求得挡土墙绕基底转动下，墙后不连续边界形状下土体的静力场，同时对对应的机动场进行分析，找出了满足所有速度边界条件和静力边界条件的应力场，得到绕墙基转动下挡土墙土压力的严密解。算例表明：求解极限平衡问题真解的算法是可行的。

Rigorous solution method for earth pressure under discontinuous surface

Based on upper and lower bound theorems,according to the characters of discontinuous line of stress and velocity,the stress field and the corresponding velocity field were got by the numerical calculation to solve three kinds of boundary value problems.The weight of soil and the friction between soil and retaining wall were taken into account.The stress field satisfied with all velocity boundaries was found.The rigorous solution of earth pressure under discontinuous surface was solved.The computation result...
