摘　　要：论述了滑坡危险性分析中如何科学地估算地震力的问题。主要思路概括为：将滑坡体视为一个完整体系的结构物（或震动对象），将滑坡场点视为一个工程场点，利用比较成熟的地震危险性概率分析方法计算滑坡体未来若干年内可能遭遇的不同超越概率水平下的地震峰值加速度，这种不确定性的地震加速度是由地震预报的不确定性带入的，由此计算地震力和惯性力。最后，对地震触发滑坡的机理展开讨论。The authors have discussed the problem of the earthquake force in landslip hazard analysis. The main method is: the authors regard the body of landslip as a structure of complete system, and the landslip site as an engineering one. They have used well-considered hazard analysis to caculate the earthquake peak acceleration of the landslip which will experence probability in the future years. This uncertainty of earthquake acceleration was caused by that of earthquake prediction.
