摘要
基于加锚节理岩体力学模型应用三维弹粘塑性有限元法,对小湾拱坝右岸缆机基础高边坡的开挖过程和加固措施进行了数值仿真计算,进行了两种设计方案的比较和优化分析,对缆机荷载移动、地下水位、岩体强度参数等影响因素进行了敏感性分析,并在此基础上评价了边坡支护加固措施和边坡的稳定性。
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.
