摘要
根据三峡库区典型滑坡火石滩滑坡的结构及变形特征,分析滑坡形成的原因。对该滑坡进行大地形变监测、地下水位监测、滑体深部位移监测和宏观监测;依据监测资料并考虑到未来三峡水库蓄水,认为火石滩滑坡目前处于潜在不稳定状态。滑坡体在饱水及水库蓄水后,将处于临界蠕滑或失稳状态。结合滑坡体实际对滑坡防治进行初步研究,建议采用回填压脚支档为主、辅以排水的综合治理措施。
Based on the structure and deformation characteristics of the Huoshitan landslide, the causes of landslide formation were analyzed. The monitoring to earth transmutation, ground water line, deep slide mass displacement and macroscopic state have actualized for Huoshitan landslide. According to the monitoring data and taking the impoundment of Three Gorges reservoir into account, the Huoshitan landslide was under unstable state. The landslide is in critical creeping motion or at the unsteady state after impoundment of reservoir. Considering the practical situation and the study of treatment for against slope, the backfill toe weight and drainage system are adopted to keep the slide mass stable.
