Research on Design and Calculation Method of Double Row Portal Anti Slide Pile

为研究门式双排抗滑桩设计计算方法,针对门式双排抗滑桩的受力特点,将其从滑面处分为受荷段和嵌固段,从工程上常用的地基系数“K”法出发,推导出不同特征段的微分方程和内力位移关系,并结合滑面、桩底边界条件以及桩顶的位移协调条件,推导出门式双排抗滑桩的计算表达式。

In order to study the design and calculation method of portal double row anti slide pile,according to the mechanical characteristics of portal double row anti slide pile,the sliding surface is divided into loading section and anchoring section.Based on the foundation coefficient“K”method commonly used in engineering,the differential equations and internal force displacement relations of different characteristic sections are derived.Combined with sliding surface,pile bottom boundary conditions and displacement coordination conditions of pile top,the double row portal anti slide pile is derived Calculation expression of row anti slide piles.
