观斗山背斜地区顺层岩质滑坡影响因素与形成机制分析

针对宜宾市观斗山背斜地区特殊的地质构造和岩性特征导致滑坡地质灾害多发的情况,该文以水井湾滑坡为研究对象,开展对该地区顺层岩质滑坡地质灾害的影响因素和形成机制分析,通过现场调查,了解水井湾滑坡的形态特征、边界情况以及滑坡的物质组成情况。再通过实验室相应的土工试验,得到水井湾滑坡相关的物理力学参数,计算出其稳定性。通过总结水井湾滑坡的影响因素和形成机制,以期为该地区顺层岩质滑坡的防治提供参考,有利于宜宾市对象鼻片区的规划开发。

In view of the frequent occurrence of landslide geological disasters caused by special geological structure and lithologic characteristics in Guandou Mountain anticline area of Yibin City,this paper takes Shuijingwan landslide as the research object.in this paper,the influence factors and formation mechanism of bedding rock landslide in this area are analyzed,and the morphological characteristics,boundary conditions and material composition of Shuijingwan landslide are understood through on-site investigation.Then through the corresponding geotechnical tests in the laboratory,the physical and mechanical parameters related to Shuijingwan landslide are obtained,and its stability is calculated.By summarizing the influence factors and formation mechanism of Shuijingwan landslide,it is expected to provide reference for the prevention and control of bedding rock landslide in this area,which is beneficial to the planning and development of the object nose area of Yibin City.
