地震滑坡灾害评估中地震影响因素的联合应用

地震滑坡灾害是一种致灾性极高的地震次生灾害，其中的地震触发因素是导致滑坡发生的重要影响因素．可以表征地震影响因素的参数有多种，但它们代表地震动水平的能力有差异，对灾害评估预测结果有很大影响．因此，本文提出利用层次分析法将多种地震动参数联合应用以弥补不同参数间存在的不足和差异．计算实例表明, 参数联合应用所得评估结果与实际破坏情况最为接近，优于参数单独使用所得评估结果，说明该方法是可行的．文中给出的参数联合应用的方法对于其它地震灾害的评估也有很重要的借鉴意义． 

Application of multiple ground motion factors in earthquake-induced landslide hazard evaluation

Earthquake-induced landslide is a catastrophic earthquake secondary disaster.The triggering factor of earthquake plays very important role in this kind of disaster.Many parameters can represent the influence factor of the earthquake.However,there are differences among their representative capabilities,which will exert great influence on the evaluation/forcasting result if these parameters are used.A method of combining the parameters into one is given based on Analytic Hierarchy Process(AHP).The discrepancy and difference between parameters can be compensated in this way.The calculated example shows that the result based on the combination of these parameters is far better than those obtained from single ones.This proves the feasibility of applying this method to evaluation of other kind of earthquake hazards.
