摘　　要：为了考虑挡墙位移与深度对土压力大小及分布规律的影响,使计算结果更加接近实际情况,根据水平承载桩土抗力计算方法建立了可以考虑位移及深度非线性影响的挡墙土压力计算模型,并对其主要参数水平地基系数KN的取值进行了分析。通过对计算模型的试验验证显示:该模型能比较准确地计算土压力的大小,并且能够较好地反映土压力随深度的分布规律。表明该方法简便、实用,可为挡墙设计土压力的计算提供一定参考。This paper discusses the influence of displacement and depth which governs the magnitude and distributions of earth pressure acting on retaining wall.The earth pressure calculation model of the nonlinear influence of depth and displacement is put forward based on the soil resistance of the horizontal loaded piles.The main parameter—horizontal foundation coefficient of this model was analysed.Calculation results can well reflect the magnitude and distribution of earth pressure,which was confirmed by experiments.It is indicated that the presented calculation model is feasible and reliable.Some useful reference for the design of retaining wall can be provided.
