摘　　要：论证并探讨了地震动触发滑坡体滑动的机理，认为地震时的坡体波动振荡在斜坡岩土体变形破坏过程中产生三种效应：累进破坏效应、启动效应和启程加速效应，并得出了一些既有理论研究意义，又有一定实际应用价值的论断。Through researching,it is suggested that the slope body vibration would produce three effects in the forming process of landslide while earthquake,which include progressive crack, starting and acceleration on initial path It is put forward that the set out intense velocity would produce a no neglected effect on the sliding process of the landslide and may transfer some short distance with slow speed landslide to long distance with high speed one and increase its destructiveness

关 键 词：滑坡 累进破坏效应 启动效应 启程加速效应
