本文推广了苏联卡岡(М.Е.Каган)提出的挡土墙土压力非线性分布的计算方法,得到了填料面为单一斜坡、任意墙背坡度下土压力与土压力分布、合力作用点等的计算公式。论证了这一方法与一般库仑方法的异同点;证明了这一方法与前人的一些实验结果甚为接近,是对库仑理论的合理改进。 This paper generalizes the calculation method of nonlinear distribution of earth pressure on retaining wall proposed by М.Е. Каган, and obtains the distribution and combined force of earth pressure and earth pressure under the condition of a single slope and arbitrary back slope. Etc. formulas. The similarities and differences between this method and the common Coulomb method are demonstrated; it is proved that this method is close to some of the previous experimental results and is a reasonable improvement of Coulomb theory.
