摘　　要：抗滑桩因其具有抗滑能力强 ,适用条件广泛 ,对滑坡的根治性能好等突出优点而被广泛地应用于滑坡治理中。但由于以往“表格”计算方式的限制 ,在其设计应用中存在一些不尽如人意的地方。对滑坡治理中抗滑桩的应用、桩身形变、内力、钢筋混凝土桩的结构设计进行分析 ,给出了不同地基系数条件下的桩内力表达式、不同位移及转角边界条件下桩身变形 ,以及钢筋混凝土桩的结构形式。编制了从滑坡推力计算至桩结构设计的全套应用程序 ,从而使抗滑桩的分析快捷、准确、实用性更强。Anti slide pile is one of the main structures of slope prevention. Because of its good advantages such as strong resistant power, broad application condition and good curing to slope, anti-slide pile is widely used to prevent slide. But there are some problems in design and application, for the limit of 'table calculation' ways. This paper analyzes the application of anti slide pile, the deformation of pile body, internal force, structure design of reinforced concrete pile. Then the calculation equations of pile internal force, the pile body deformation under the condition of different displacement and turning angle, and structure form of reinforced concrete are given. The program of slope push force calculation and pile structure design are also given. So analysis of anti slide pile becomes quick, accurate and applied.
