摘　　要：从被动桩和土拱效应的概念出发 ,推导出计算任意桩型抗滑桩极限阻力的半经验半理论公式。运用由点到面、由面到空间的方式 ,将 3道安全系数穿插于建模过程中 ,给出一种新的抗滑桩工程整体设计方法。将公式和方法应用于长江三峡库区的丰都县楠竹大型滑坡的抗滑桩工程设计 ,获得了良好的结果。Based on to the concepts of passive pile and soil arch effect a semi empirical formula for calculating extreme resistance of stabilizing piles for resisting land slide is deduced. The design principle of pile group is suggested based on the analysis of single pile. The method is applied to the design of landslide prevention engineering of Fengdu County located in the reservoir of the Three Gorges Project.
