Abstract: The landslide thrust force design value difiers in different safety factor definition．A discussion on the influence on the thrust value in different safety definition is proposed．The thrust force design value adapted landslide load-increased fac- tor is the maximuMand the one in the same safety strength factor is bigger than that in double strength safety factor．The trust value analysis using two reduction factors is put forward at the first time．It conforms to slope’S realities best．The val- He in Imbalanced Trust Method should adjust a little because of landslide load-increased factor and the contribution for the resistance is without the consideration．The method using double strength safety factors for the thrust is put forward，which provides reference and discussion SO as to gradually become a consensus．

Key words: slope engineering, landslide thrust force, landslide load-increased safety factor, double strength factors

摘要： 不同安全系数定义下抗滑桩上推力设计值不同，探讨了不同安全系数下对滑坡推力设计值的影响，采用下滑 力超载储备安全系数计算的滑坡推力设计值最大，同一强度储备安全系数的推力设计值大于双强度储备安全系数 下的滑坡推力设计值。提出了双强度储备安全系数的滑坡推力计算，此中定义更符合边(滑)坡破坏的实际情况， 传统的滑坡推力设计采用下滑力超载储备安全系数、也没有考虑滑体的积极因素，传统滑坡推力设计值有较大的下 调空间，所以提出采用双强度储备安全系数计算滑坡推力，供大家参考和讨论，以逐渐形成共识
