摘要
基于综合刚度原理和双参数方法,提出了进行抗滑桩全桩位移和内力计算的有限差分法,推导了相关公式,编写了实用的计算和图形处理程序。由程序实例计算图形处理结果,探讨了滑坡推力分布形式、双参数m和1/n,以及不同桩底条件对抗滑桩位移和内力的影响,对抗滑桩的设计具有指导作用,有效提高了抗滑桩设计的经济性和安全性。
Based on the composite stiffness principle and bi-parameter method, a finite difference method is proposed for the calculation of whole displacement of anchor-stabilizing pile and the internal forces. The corresponding formulae are derived and some practical programs are compiled for calculation and figure treatment. The effects of distribution of thrust force of landslide, bi-parameter of m and 1/n, as well as different conditions at pile bottom, on the displacement and internal force of the anti-sliding pile are discussed through the calculation and figure treatment of practical examples. It can be a guide in the design of anti-sliding pile to increase the economy and safety of the design.
