摘要

对挡土墙背离填土绕墙脚转动时墙后滑裂土体的应力状态进行了详细分析，建立了墙后滑裂体水平土层墙面反力、滑裂面反力、土层间剪力和土层竖向土压力强度之间的关系式。为了考虑挡土墙绕墙脚转动时墙脚局部土体并未达到极限状态，对墙面摩擦角、滑裂面土体的内摩擦角予以折减。在水平土层单元法的基础上，考虑水平土层间剪力作用、每一土层的墙面摩擦角和滑裂面水平倾角等的变化，建立了土层竖向土压力强度的逐层渐近的计算方法，并给出了挡土墙主动土压力强度、土压力合力及其作用位置的计算公式。经比较表明：挡土墙主动土压力分布曲线与试验结果基本一致，计算得的主动土压力系数与试验结果很接近，比库仑解大；计算得出的滑裂面为一曲面，其顶部开裂宽度比库仑滑裂面小，与工程实际相符。

Abstract

The stress state of the sliding soil behind a rigid wall rotating about base is analyzed in detail. The relations among the reactions on wall and sliding surface

and shear stress and vertical pressure of the horizontal soil strata are established. The friction angles of the wall and sliding surface are reduced in order to consider that the soil near base don’t reach the limiting equilibrium state. Based on the horizontal soil slice element method

the stratum by stratum calculational method is set up to obtain the vertical earth pressure acting on the surface of stratum by considering the shear stress of the strata

the change of angle of horizontal of the failure line and the friction angle of the wall. The unit earth pressure

the resultant earth pressure and the point of application of the resultant earth pressure on the retaining wall are also obtained. It is demonstrated that the obtained unit earth pressure is consistent with the experimental observations; and the resultant earth pressure is larger than that of coulomb’s solution. The width of the topper curved sliding surface is smaller than that of coulomb’s solution; but it is consistent well with the engineering observations.
