摘要
滑坡的失稳是一个渐变到突变的过程,破坏前会有一些预兆,捕捉这些信息并及时发现问题、采取处理措施是滑坡监测的主要目的。对小浪底某滑坡进行综合监测研究,在滑坡的关键位置设置25个地表变形监测点和3个深部变形监测点,所有监测点组成多层次综合监测系统,进行监测研究。分析监测数据可知:该滑坡体地质结构大致分为前部滑塌体、中后部滑移体和后缘拉裂体。坡体的力学性质分区大致为崩坡积物、碎裂岩体、裂隙、基岩,由此分析了滑坡体表面及深部变形的趋势和影响因素。
Landslide instability is a gradual change to the process of mutation and there will always be some warning before the destruction.The main purpose of landslide monitoring is to find and take measures.This paper studied on landside comprehensive monitoring in Xiaolangd i,by installing 25 surface defor^nation monitoring points and 3 deep defor^nation monitoring points at key locations landslide,which integrated multi-level monitoring system by all the monitoring points.The monitoring data analysis shows that:the geological structure of the landslide was divided into front slump,in the postmedian of the sliding mass and a trailing edge crack body.The mechanical divisions are colluvial slope sediments,cataclastic rock mass,fracture,bedrock four classes.And the deformation trend and influencing factors of the landslide surface and the deep part were analyzed.
