“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。 “5.12 ” Wenchuan earthquake Longmenshan area developed high earthquakes, usually occurring in the 10 ~ 11 degree of extreme earthquake zone, this disaster is difficult to predict, occur fast, likely to cause heavy losses of life and property. Based on the field investigation at Chuanzhu Ping in Longchi Township, this paper analyzes the projectile accumulation formed by typical earthquake-induced landslides and explores the effect of the earthquake acceleration due to the terrain amplification effect and the motion program of the collapsed and ejected.
