Numerical Simulation of Excavation of Abutment Slope at Left Bank in Dagangshan Hydropower Station

Yang, Kun / Ma, Zhi Chao / Han, Hao

The abutment slope at left bank in Dagangshan hydropower station has complex geological conditions with deep fractures, developed faults and unloading crack. The excavation will influence the stability of the slope. To evaluate the slope stability, the finite element model of this abutment slope was built in this paper to study the deformation, stress and plastic zone distribution of the slope during the excavation. The potential failure location of the slope is forecasted, some suggestions are proposed to be helpful to keep the stability of the slope.
