摘　　要：挡土墙库伦土压力计算受墙后填土形状、填土之上荷载分布及大小的影响,其计算公式不唯一。文章针对墙后填土不同破裂面的类型,分类讨论并总结梳理各类情况下挡土墙破裂角及土压力计算公式,并在实例解析中通过了北京理正岩土软件验证,为初学者提供学习的方向和思路。The calculation of Coulomb earth pressure of retaining wall is affected by the shape of the filling behind the wall,the distribution and quantity of load on the filling,and the calculation formula is not unique.According to the types of different fracture surfaces of the filling behind the wall,this article classifies,discusses and summarizes the calculation formulas for the fracture angle and earth pressure of the retaining wall under various conditions,and the formulas has passed the verification of Beijing Lizheng Geotechnical Software in the case analysis.It can guide the learning in the field for beginners.
