摘　　要：利用极限分析上限法,对一种在刚性平动模式下计算挡土墙被动土压力的方法进行了分析,推导了平动模式下m个刚性三角形滑动块被动土压力系数的目标函数,并利用Matlab优化工具箱优化该目标函数,得到了挡土墙被动土压力系数的上限解。Using the upper bound limit analysis require, the calculating method of passive earth pressure against retaining walls under rigid translation mode was analysed. The objective function of passive earth pressure coefficient of m rigid triangular sliding blocks under translation mode was derived, and was optimized by Matlab optimization toolbox, and we obtained the upper limit solution of passive earth pressure coefficient against retaining walls.
