| 摘 要： | 用有限元计算了单江拱坝右坝肩岩体的变形,着重分析了断层 F1 对于坝肩岩体变形的影响。用极限分析方法,计算了断层、层面等结构面切割形成的块体的抗滑稳定安全系数。结果表明,在一定范围内断层 F1 对于坝肩岩体的变形具有很大的影响,块体不能满足规范规定的抗滑稳定要求,需要加固。并对加固方式提出了建议。

| Abstract: | At first FEM is used to calculate the deformation of the right abutment of the Danjiang arch dam; and the influence of the fault F1 on the deformation of the abutment is analyzed emphatically. Then the limit stability analysis method is used to calculate the stability factor of safety of the blocks cutting by the fault and bedding layers. The results show that the fault has significant influence on the deformation of the abutment within a certain extent; the blocks can’t meet the stability requirement and reinforcement is required. Finally, on the basis of the results some reinforcement measures are suggested. |
