摘　　要：＂5.12＂汶川大地震龙门山地区发育地震高位滑坡,通常发生在10-11度的极震区,这种灾害难预测,发生速度快,容易造成惨重的生命和财产损失。本文通过在龙池乡川主坪的实地调查,对典型地震抛射滑坡形成的抛射堆积体进行剖析,探究地震加速度受地形放大效应的影响效应及崩塌被抛射的运动程式。The Longmen Mountains occured thrown landslide on high slope when ＂5.12＂ Wenchuan earthquake happened.It was usually emerge in 10 degrees to 11 degrees zone.This disaster is too difficult to predict,so it occur fast and cause heavy loss of life and property.This article,through investigation in the Chuanzhuping of Longchi Town,analyzed a typical earthquake thrown landslide,and explored the effect by topographic amplification of earthquake acceleration and motion programs of thrown landslide.

关 键 词：汶川地震 高位滑坡 运动程式 地形放大效应
