摘要:
水库滑坡是三峡库区多发性的地质灾害,其主要诱发因素是库水位升降和降雨,三峡库区重大危险性滑坡专业监测已实施多年,积累了丰富的监测数据。谭家河滑坡是长江干流上重大涉水滑坡,自2006年实施专业监测以来该滑坡持续变形。结合专业监测、库水位和降雨等资料,分别提取了降雨和库水位变化因子,深入细致地分析了滑坡变形特性,给出了该滑坡的变形演化模式,获得了一些新的认识:库水位抬升所产生的付托减重效应对该滑坡变形有一定影响,但影响有限,滑坡变形的主要诱发因素是降雨,雨型、雨强和年降雨量对滑坡变形都有较大的影响。分析成果可为水库型滑坡分类、专业监测系统优化和减灾防灾技术选择提供参考。
Abstract:
Reservoir landslide is the frequent geological disaster type in the Three Gorges Reservoir area, the landslides are triggered by water level fluctuation and rainfall. The landslide monitoring has been implemented in the Three Gorges reservoir area for many years, it provided an improved insight into slope performance associated with water level fluctuations through a large number of monitoring data. The deformation of Tanjiahe landslide, which was triggered by water level rise and rainfall, can be given from the monitoring data since 2006. How to analyze the landslide deformation is worth exploring. The deformation characteristics of landslide were analyzed based on monitoring, water level and rainfall, the deformation mechanism of landslide was studied. The results shows that rainfall is the main inducing factor to the deformation of Tanjiahe landslide, while the water level rising has limited influence on the landslide deformation. The study achievement can provides a reference for the classification of reservoir-induced landslide, optimization of deformation monitoring, prevention and control of the reservoir-induced landslide.
