摘　　要：从表层混凝土碳化、混凝土强度、坝面风化侵蚀、坝体开裂、挡水面渗漏溶蚀、大坝刚度等方面,对已运行40多年的佛子岭连拱坝的耐久性进行了全面分析;对该坝运行中多次遭受不利运行工况的危害机理和程度作了重点分析研究。从设计、施工、运行管理全过程,总结出影响该坝耐久性的一些主要问题,指出重视和实施科学运行,以保证大坝的安全和耐久性,具有普遍的现实意义。The comprehensive analysis was conducted for the durability of Foziling multi-arch dam which has been put into operation for over 40 years, from the aspects of surface concrete carbonation, concrete strength, dam surface weathered erosion, dam body cracking, impounding surface leakage corrosion and dam stiffness. The study was emphasized on the harmful mechanism and degree resulted from adverse operation working conditions during over-years operation. It concluded the main dements effecting on the durability of Foziling multi-arch dam from the overall process of design, construction and operation management. It indicted that it is realistic to conduct and pay high attention to the scientific operation so as to ensure dam safety and durability.
