| 摘 要： | 采用有限单元法对作用于刚性挡土端上的被动土压力进行数值分析，土体采用弹塑性的Mohr-Coulomb本构模型，在土与结构接触面问引入无厚度的Goodman接触单元，接触面上剪应力和剪切位移采用弹塑性的本构模型，研究了不同的挡土墙的变位模式、不同墙面摩擦特性以及土体变形特性等因素对土压力大小和分布的影响。

| Abstract: | In this paper,numerical analyses for passive earth pressure problems of the rigid retaining wall are performed,aiming at improving understanding of the factors governing the magnitudes and distributions of the earth pressures on retaining walls. Passive earth pressure problems are analyzed by using a Mohr-Coulomb constitutive model of soil. A method to describe the frictional behavior between soil and walls is proposed using the elastoplastic joint elements. The computed variations of earth pressure with wall displacement in passive states explain well the influence of the wall friction and the wall movement. |
