库水位变化下对水库滑坡稳定性影响的预测

Effecting and forecasting of landslide stability with the change of reservoir water level

本文在分析库水位与滑坡稳定性的一般规律的基础上 ,对某水库滑坡进行了考察 ,分析其初期蓄水过程中滑坡的位移动态和代表性测点位移的规律 ,确定最危险水位 ,进行稳定性计算中的参数反演 ,在此基础上 ,考虑地下水渗透的滞后性 ,进而预测了未来蓄水及潜在的库水位下降情况下滑坡稳定性与库水位的关系。

Based on the analysis of relationship between the level of reservoir water and stability of landslide,a reservoir landslide is investigated.The law of the landslide displacement at the representative measuring points during the elementary water storage period is analyzed,the most dangerous water level is determined,and the parameters for stability analysis are obtained by back analysis.Then,considering the rearfalling,relation between stability of landslide and level of reservoir water is prodicted for the case of storing water and falling of water level in the future.
