三峡库区滑坡的水文地质分析
Hydrogeology analysis of landslides in Three Gorges reservoir area
摘要
Abstract
The geological hayards occur with high frequency in Three Gorges reservoir area. The landslide disasters have caused serious loss to the local economic development, the life and property. How to predict the landslides is one of the key problems for preventing hazards and reducing economical loss and casualties. The rainfall is the dominant exterior factor triggering the landslides. Through the statistics and correlation analysis for the observation data of rainfall and deformation of section piles from the Zigui early-warning station in many years, it could be found that if the rainfall reaches a specific threshold value,the probability of landslide increases rapidly. Based on the topography, geological structures and lithology combination in Zigui County, the relations between pile deformation and precipitation condition for Guojiazhai Station and Lijiawan Station were obtained by means of statistical method. It could be found from the obtained results that the specific threshold value of rainfall varied with different geological environment and lithology. The real-time sudden landslide is expected to be predicted based on statistical analysis of monthly precipitation.关键词
