摘要
豫西地区位于我国地势第二级阶梯向第三级阶梯的过渡地带,为河南省内滑坡易发区。锁固型滑坡具有聚能效应,易形成高速远程滑坡,直接威胁着工程建设安全、生态环境和人民的生命财产安全。系统地分析了豫西地区的地质条件和滑坡的诱发因素;基于锁固型滑坡的工程地质特征、变形演化机理、锁固段存在的形式和赋存位置,提出豫西锁固型滑坡分布类型主要有顺层直剪式、跨层斜切式和挡墙式,并给出了槐扒滑坡、风脉寺滑坡和东苗家滑坡的工程案例。
The western Henan province is located at the transition zone of the second step to the third step of China's terrain and is the landslide-prone area.The locked section landslide with gathering energy effect,is usually easy to form a high speed and long range landslide,which directly threatens major projects construction safety,ecological environment and the lives and properties security.This paper systemically analyzed the geological conditions and the triggering factors of the landslide in western Henan province.In this paper,the locked section landslide in western Henan province was mainly subdivided into three types based on the engineering geological characteristics,deformation evolution mechanism,the existing form and the position of the locking section,namely:bedding direct shear type,cross-layer oblique cut type,retaining wall type;and the Huaiba landslide,Fengmaisi landslide,and Dongmiaojia landslide were presented as engineering cases.
