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。 According to the investigation of the stability and displacement of some mixing pile retaining walls in Shanghai, from the perspective of controlling deformation, it is recommended that when designing cement retaining walls, the overall stability safety factor K>1.2, anti-uplift stability coefficient K_s>1.8, anti-slip The stability coefficient K_h>1.3. At the same time pointed out the existing problems in the traditional method for calculating the anti-overturning stability coefficient of the mixing pile retaining wall, and gave an improved method to calculate the anti-overturning stability coefficient, and suggested to take the anti-overturning stability coefficient K_q~1 during design. 1.4.
