摘要：

基于扰动状态概念（DSC）,结合库伦土压力理论研究平动位移模式下刚性挡土墙的土压力计算方法.以挡墙平动位移量为扰动参量,建立扰动度函数表达式.提出扰动摩擦角概念,建立扰动摩擦角与扰动度之间的关系公式.参照库仑土压力理论,分析任意扰动状态下土楔的最不利受力情况,得到平动位移模式下基于DSC理论刚性挡土墙土压力计算公式.算例分析表明：在任意扰动状态下,基于DSC理论的刚性挡墙土压力计算公式所预测的土压力大小、分布以及土压力系数均与模型试验结果比较吻合.
Abstract:

Through combining with the Coulomb’s earth pressure theory, the method of calculating earth pressure against rigid retaining wall under translation mode was studied based on the disturbed state concept (DSC). The disturbance function was established by taking the movement of rigid retaining wall as the disturbed parameter. The disturbed frictional angle concept was proposed and the relationship between the disturbed frictional angle and the disturbed degree was obtained. By analyzing the forces on the most unfavorable soil wedge at arbitrary disturbed state, the general formulas for calculating the earth pressure against rigid retaining wall under translation mode were established based on DSC theory. Calculation results shows that the predicted magnitude and distribution of earth pressure and the coefficients of earth pressure agree well with those of the model test at random disturbed state.
