根据土拱效应原理和摩尔应力圆,获得了考虑墙背倾角影响的墙背法向主动土压力系数,然后根据水平微分滑裂体的竖向静力平衡得到了平移模式下的倾斜刚性挡土墙法向主动土压力、法向主动土压力合力及其作用点高度等的计算式.进一步分析了墙背倾角、墙土摩擦角和填土内摩擦角对法向主动土压力及其系数、法向主动土压力合力及其作用点高度的影响.%According to soil arching effect and Mohr stress circle,a new formula of the coefficient of the normal active pressure was put forward considering effect of inclined angle of the wall surface.According to vertical static equilibrium of differential level sliding soil,new formulas of the normal active earth pressure on titled rigid retaining wall,the normal active earth force and the height of its application were derived.In addition,the effects of the inclined angle of the wall surface,the internal friction angle of backfill and the wall-soil friction angle on those formulas were investigated.
