陡倾片麻岩滑坡影响因素分析
Analysis of Factors Affecting Steeply Dipping Gneiss Landslides
摘要
Abstract
The region between estuaries of Lanlingxi Creek and Shanmu Creek is a unique metamorphic rock area in the Three Gorges Reservoir Area,and the landslides developed in this area have special characteristics.In this paper,the Lanlingxi landslide in Three Gorges Reservoir Area is taken as an example.Based on two years'monitoring data in time series,the process analysis method and quantitative analysis method are used to study the factors affecting landslide deformation.The results show that:the reservoir water is the main factor affecting the landslide deformation.When the reservoir level is higher than 160 m,the reservoir water rises and falls at different rates,and strong deformation occurs in the landslide of Lanlingxi Creek.When the reservoir level is lower than 160 m,the rate of the reservoir water rises and falls does not have any obvious effect on the landslide deformation,and the landslide is in the period of slow deformation.Rainfall is a secondary factor inducing landslide deformation.When the reservoir water falls or rises coupled with strong rainfall,the landslide is induced to deform violently.Especially,during the period of low water level,the strong rainfall promotes the landslide deformation.Combined with the field investigation and monitoring data,it can be seen that the landslide shear exit is located near the elevation of 155 m.The research results provide scientific basis for monitoring and early warning,prevention and control works of the landslides in Lanlingxi Creek,and provide reference for the analysis of the causes and deformation mechanisms of the same type of water-related rocky landslides.关键词
