Deformation mechanism and stability evaluation for the left abutment slope of Jinping I hydropower station
Abstract There are very complicated engineering geological conditions in the left abutment slope of the Jinping I hydropower station with the stress-release opening of fractures along existing faults and where lamprophyre veins are present. Prior to the excavation for the dam, the slope generally consisted of a thick marble mass between fault $ f_{5} $ and the free face. As a consequence of the removal of some of the marble to create the abutment, the stability of the slope would be reduced. The paper reports the stability assessments undertaken, based on engineering geological analysis and block theory and the results of the analysis of key rock masses under four conditions: natural, heavy-rain, earthquake and heavy-rain plus earthquake.
