阿海水电站左岸高边坡安全监测分析

Monitoring and analysis on safety of high slope on left bank of A'hai Hydropower Station

阿海水电站高边坡地质条件复杂、岸坡陡直,边坡开挖工期短,支护强度大,立体交叉作业面相互干扰。为保证在整个大坝施工过程中的边坡稳定,及时掌握边坡变化情况,对边坡进行了有效的安全监测,主要监测项目包括位移、地下水位、边坡变形等。对已开挖支护完成的边坡监测资料的分析表明:左岸坝肩边坡目前处于稳定状态。安全监测为施工的顺利进行提供了保证。

The high slope of A＇hai Hydropower Station is characterized by complicated geological conditions,steep bank slope,short construction period,intensive excavation and support construction and inter-disturbance of cross operation surfaces.In order to guarantee the stability of slope during the construction,the slope variation was monitored in the construction.The monitoring contents included displacement,underground water level,slope deformation etc.The analysis result of the monitored data of the slope having been excavated and supported showed that the slope on the left bank of the station is in stable state.The safety monitoring guaranteed the smooth construction.
