摘　　要：将三剪统一强度理论应用到挡土墙土压力计算的水平层分析法中,并将计算结果与基于Mohr-coulomb强度准则的计算结果进行对比分析,证明了三剪统一强度理论全面考虑三个主剪应力及其面上的正应力对材料强度的影响是非常合理的,其计算结果和实测结果高度吻合.In this paper, the triple-shear unified strength theory is applied to the horizontal layer analysis method for earth pressure calculation of retaining wall, and the calculation results are compared with the results based on the Mohr-coulomb strength criterion. It is proved that in the triple shear unified strength theory, it is very reasonable to consider the effect of three main shear stresses and the positive stress on its surface on the strength of the material, and the calculated results are highly consistent with the measured results.
