三峡库区白水河滑坡变形分析及评价

Deformation Analysis and Evaluation of Baishuihe Landslide in Three Gorges Reservoir Area

针对三峡库区白水河滑坡体局部复活、开展对其实施复合预警监测。通过对三峡库区白水河滑坡的地表宏观变形和监测数据分析,研究库区水位变化和降雨对滑坡的影响机理,并对白水河滑坡变形现状及趋势进行评价与预测,结果认为,降水坡水库水位下降是滑坡复活的诱发因素,两者叠加作用造成滑坡体稳定性下降。通过变形加速度及裂缝分期配套分析,截止2010年7月滑坡仍处于匀速变形阶段。

Aiming at the local resurrection of the Baishui River landslide in the Three Gorges Reservoir area, the compound early warning monitoring was carried out. Based on the analysis of the macroscopic deformation and monitoring data of Baishuihe landslide in the Three Gorges Reservoir area, the influence of water level change and rainfall on landslide is studied, and the present situation and trend of Baishui River landslide deformation are forecasted and predicted. The results show that the precipitation The decline of water level is the predisposing factor of landslide resurrection, and the superposition of the two causes the landslide stability to decrease. Through the deformation acceleration and fracture staging supporting analysis, as of July 2010 the landslide is still in the uniform deformation stage.
