某岩质滑坡多层滑带勘查方法应用研究

Research on Application of Exploration Method for Multilayer Slip Zone of a Rock Landslide

巫山峡谷地区地质构造发育,岩体节理裂隙发育,岩土结构复杂多变。滑坡具有滑体厚度变化大、滑带特征复杂的特点,不易鉴别。针对以上难点,文章基于深层岩质滑坡勘理论,采用钻孔深部位移监测、分布式光纤传感技术及岩矿鉴定方法对正在变形滑面进行锁定,分析滑坡其主要滑面和次级滑面分布位置及物质成分,为滑坡勘查提供参考。

The geological structure in Wushan canyon area is developed,the rock mass joints and fissures are developed,and the rock and soil structure is complicated and changeable.Landslide is characterized by large thickness variation of sliding body and complex characteristics of sliding zone,which makes it difficult to identify the real sliding zone.In view of the above difficulties,this study is based on the theory of deep-seated rock landslide exploration,and uses borehole deep displacement monitoring,distributed optical fiber sensing technology and rock ore identification methods to lock the deformation sliding surface,and analyzes the distribution location and material composition of the main sliding surface and secondary sliding surface of the landslide.It provides some reference for landsl ide exploration.
