摘要
根据上海市部分搅拌桩挡墙的稳定和位移调查,从控制变形的角度出发,建议在进行水泥土挡墙设计时,整体稳定安全系数K>1.2,抗隆起稳定系数K_s>1.8,抗滑移稳定系数K_h>1.3;同时指出了传统计算搅拌桩挡墙抗倾覆稳定系数方法存在的问题,给出了计算抗倾覆稳定系数的改进方法,并建议在设计时取抗倾覆稳定系数K_q^1>1.4。
on the basis of investigating DMP retaining walls in Shanghai city, according to the control of displacement, this paper recommends that Dintegral stability safety factor K>1. 2, 2)safety factor of resisting upheaval Ks>l. 8 and 3)safety factor of resisting slippage Kh>l- 8 in DMP retaining walls. It also pointed out the problems in traditional methods of calculating safety factor of resisting overturn (Kq) and new method of calculating Kq. Finally Kq>l. 4 was recommended as well.
