STUDY OF FORMATION CONDITIONS AND TOSS MOTION PROGRAM OF HIGH LANDSLIDES INDUCED BY EARTHQUAKE
地震高位滑坡形成条件及抛射运动程式研究

Based on structural features and earthquake-induced slope response,the genetic mechanism of the typical earthquake high slope landslides can be concluded as follows:the structural plane of rock mass cut by cranny is apart from the lower limit of strong unloading zones,and is made run through to lose the bonding force with underneath rock mess by upper throwing force of P-wave and horizontal shear force of S-wave;the surface wave with huge acceleration(more than 2 g normally) arrives last and is enlarged by terrain,by which the upper surface layer of the slope is thrown out approximately horizontally or decumbent;and the earthquake-induced high slope landslide is formed.
