摘要
大坝是水电站的重要组成部分，其安全运行寿命关系到水电站的经济效益和社会效益。一般认为大坝的安全运行寿命为80～100年。由于设计、施工和管理等原因，导致大坝混凝土过早出现“老化病害”，降低了大坝的安全运行寿命，必须进行大修才能保证大坝安全运行。分析了东北水电站大坝的安全运行寿命和影响其寿命的老化病害各种现象。
Dams are important components in hydraulic power plant, the safety operation life of which is vital to the economic and social benefit. It is considered that the safety operation life is from 80 to 100 years. Because of the design, construction and management, the dam concrete ＂aging＂ comes earlier, reducing the operation life. Therefore overhaul must be carried out to ensure the dam safety. The paper also analyzes the safety operation life and phenomena effecting operation life in Northeast hydraulic power stations.
