摘　　要：土压力的分布和大小与变形密切相关。分析了目前考虑变形的土压力设计计算方法,并提出了考虑变形的土压力计算模型,对两个工程实例进行了计算分析,计算所得的主动土压力和被动土压力都在合理的范围内,显示出了该方法的合理性。On the basis of present research on the soil pressure with deformation, a new method calculating soil pressure considering deformation is presented. The two typical cases are calculated by the finite element program, the results show that soil pressure at the active zone is between soil pressure at rest and Rankine active soil pressure; and soil pressure at the passive zone is maaller than Rankine passive soil pressure.
