Monitoring and analysis on safety of high slope on left bank of A'hai Hydropower Station
Zhao Feng · Yangtze River · 2011
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.
