【摘要】 挡土墙的土压力绝大多数是非极限状态的。通过准滑移面计算挡土墙非极限状态被动土压力,结果表明,墙后非极限状态被动土压力呈非线性分布,合力随墙体位移的增大而线性增长,其作用点位置逐渐降低,在墙高的下三分点以下。更多还原

【Abstract】 The earth pressure of retaining wall is mostly non-limit state. In this paper,the passive earth pressure of non-limit state on the retaining wall is calculated by quasi-slip plane. The results show that the non-limit state passive earth pressure is nonlinear distribution. The resultant force increases linearly with the increase of the retaining wall displacement and its application point is gradually reduced and the point is lower than 1/3 of wall height.更多还原
