| 摘 要： | 在分析库水位变化与岸坡稳定性的一般规律的基础上，对某水库泄洪洞进口高边坡变形机理进行分析。然后计算分析不同水位升降条件下，蓄水＋暴雨、地震、地震＋地下水作用等三种工况的稳定性系数，确定危险警戒水位，并预测未来蓄水及库水位下降情况下泄洪洞进口边坡稳定性与库水位的关系，为蓄水后的边坡防治提供必要的理论依据。

| Abstract: | Based on the analyzing relationship between the level of reservoir water and stability of bank,the mechanism of deformation of a high rock slope in an intake of flood-discharge tunnel is analyzed. Under the conditions; impoundment and rainstorm, earthquake, and earthquake with the effect of ground water, the stability coefficient with the change of reservoir water level is calculated and analyzed. The security water level is defined. The relationship between stability of slope and reservoir water level is predicted in the case of storing water and falling of water level in the future. An essential proposal is suggested for management of the high rock slope when storing water and falling of water level in the future. |
