中文摘要：
针对抗滑群桩设计理论方面存在的问题,即荷载传递及滑坡推力分配的不确定性,基于极限分析的上限定理,给出了一种抗滑群桩的设计方法,即人为增大第一排抗滑桩的桩间距,并按极限土压力公式设计,作用在第二排抗滑桩上的荷载则按照上限定理给出。根据上述思想,并结合滑坡能量安全系数的定义和多块体体系速度场计算方法,提出了抗滑群桩的一种设计理论。
英文摘要：
In view of uncertainty of load transfer and landslide thrust distribution in design theory of anti-slide group piles and based on the plastic limit upper bound theorem,a new design method of anti-slide group piles was put forward.The method includes enlarging the space between the first row of anti-slide plies,and then using limit earth pressure formula to design.The load that acts on second row of anti-slide piles will be obtained by the plastic limit upper bound theorem.According to these ideals,and combining with the definition of energy safety coefficient and the calculation method for velocity field of multi-block,a new design method of anti-slide group piles is proposed.
