【摘要】：基于斜坡變形破壞的時空演化規(guī)律,對西南某水電站壩前右岸邊坡的穩(wěn)定性進行研究,并結合邊坡變形監(jiān)測數據,對邊坡變形與庫水位升降之間的關系進行了分析。結果表明:滑坡周邊裂縫還未形成,裂縫體系尚未圈閉,根據斜坡變形破壞的空間演化規(guī)律判斷,邊坡目前處于基本穩(wěn)定狀態(tài),不存在發(fā)生滑坡的危險;隨著庫水位的基本穩(wěn)定,邊坡變形量逐漸趨于穩(wěn)定增長,無進入加速變形階段跡象,根據斜坡變形破壞的時間演化規(guī)律判斷,目前邊坡不存在發(fā)生滑坡的危險;水位升降過程中邊坡內部分別會形成指向坡內和坡外的滲流場,其將極大地影響邊坡的穩(wěn)定性;因邊坡變形受水庫蓄放水影響明顯,建議加強水庫蓄放水過程中地表裂縫巡視及監(jiān)測數據的分析。
[Abstract]:Based on the temporal and spatial evolution law of slope deformation and failure, the stability of the right bank slope in front of a hydropower station in southwest China is studied, and the slope deformation monitoring data are combined. The relationship between slope deformation and reservoir water level rise and fall is analyzed. The results show that the cracks around the landslide are not formed and the fracture system has not been trapped. The slope is in a stable state at present, and there is no danger of landslide. With the basic stability of the reservoir water level, the deformation of the slope gradually tends to increase steadily, and there is no sign of entering the accelerated deformation stage. According to the time evolution law of slope deformation and failure, there is no danger of landslide in the slope at present, and the seepage field which points to the slope and outside the slope will be formed in the process of water level rise and fall, which will greatly affect the stability of the slope. Because the slope deformation is obviously affected by reservoir water storage and discharge, it is suggested to strengthen the inspection of surface cracks and analysis of monitoring data during reservoir storage and discharge.
