摘要

结合云南省德钦县丹达河水电站工程实例,运用刚体极限平衡法对右坝肩抗滑稳定进行研究,采用《混凝土拱坝设计规范》(SL 282—2003)中的公式及规定,分析认为未加固处理坝肩断层f12抗滑稳定安全系数偏低,不能满足规范要求,应进行必要处理。提出处理方案,对经过处理方案处理后的f12断层进行进一步分析,分析认为加固处理后的坝肩断层f12抗滑稳定安全系数能满足规范要求,拱肩断层f12加固处理方案有效。
In accordance with the actual engineering case of Dandahe Hydropower Station Project in Deqin County of Yunnan Province,the formulas and specifications defined in the Design Specification for Concrete Arch Dam( SL 282—2003) are adopted for analyzing the anti-sliding stability of the right abutment of its arch dam with the rigid limit equilibrium method. The analysis indicates that the safety factor of the anti-sliding stability of the fault of f12 at the abutment a is a little bit lower and cannot meet the requirement of the specification concerned,thus necessary to be treated. Therefore,the relevant treatment scheme is proposed,and then the further analysis on the fault of f12 after the treatment with the scheme is accordingly made. The analysis considers that the safety factor of the anti-sliding stability of the fault at the abutment can meet the requirement of the specification,and hence,the strengthening scheme for the fault of f12 is effective as well.
