“8·12”山阳滑坡视向滑动特征与运动过程
Characteristics of Apparent Dip Slide and Movement Process of the 8.12 Shanyang Rockslide
摘要
Abstract
At 00:30 a.m.August 12th 2015,a rockslide with the volume of 1.68 million cubic meters occurred in Zhongcun town,Shanyang in Shaanxi province,which resulted in a catastrophic rockslide with 8 death,57 persons missing and nearly 0.5 billion RMB direct economic loss.Based on the investigation of geometric dimension,structure of sliding rockmass and the shear outlet,the geological conditions of apparent dip slide of the rockslide were analyzed according to the following factors including Bedding block-broken body,Inclined rockmass barrier,Apparent dip exiting,driving-rock mass sliding and the slide resisting block;and it was considered that the Shanyang rockslide took on typical characteristics of apparent dip slide which included long-term creeping along the dip angle and intercalated sliding in the slide bed,and overall slide with high-locality along the apparent dip angle.By the means of analyzing the movement process and the structure distribution of the sliding mass,the movement process of the rockslide can be divided into apparent dip shear slide zone,main slide accumulation zone,collision and retracing accumulation zone,fragment scattering zone.关键词
