目前采用的滑坡推力计算公式(传递系数法)中缺少了抗滑桩的支护抗力参数,造成计算误差。在基于强度折减安全系数的传递系数隐式解法基础上,考虑桩与滑坡体的相互作用,在条块的受力体系中加入抗滑桩的水平反作用力,然后按照设计安全系数对滑面强度参数进行折减,使得最后一个条块的剩余下滑力刚好等于0,此时对应的水平反作用力就是作用在桩上的水平滑坡推力设计值,按此水平滑坡推力加固滑坡后的稳定性系数正好等于设计安全系数。 The currently used landslide thrust calculation formula (transfer coefficient method) lacks the parameters of supporting resistance of anti-slide piles, causing calculation errors. Based on the implicit solution of the transfer coefficient based on the strength reduction safety factor, consider the interaction between the pile and the landslide, add the horizontal reaction force of the anti-slide pile to the force system of the bar, and then follow the design safety factor on the slip surface. The strength parameter is reduced so that the remaining sliding force of the last bar is exactly equal to 0. The corresponding horizontal reaction force is the horizontal landslide thrust design value acting on the pile. The stability factor after the landslide is strengthened by the horizontal landslide thrust. Just equal to the design safety factor.
