| Abstract: | Based on the model of reinforced jointed rock masses, numerical simulations on the excavation process and the reinforcement measures of the cable-machine foundation slope in the right abutment of Xiaowan arch dam are implemented by 3-D elasto-viscoplastic FEM. Two design schemes are considered and comparedwith each other, and the sensibility to factors including load mobility, variation of groundwater level etc. is analyzed. Based on these research works, the effect of the reinforcement measures and the stability of the slope are evaluated. |
