东北地区的一些混凝土大坝在经历了几十年或十几年的运行之后,即发生程度不同的风化破坏,有的已不能维持正常的运行,而不得不进行补修,例如丰满大坝、云峰大坝,参窝大坝等。考察这些大坝的破坏形式和探讨其破坏原因,寻找其固有的规律性,对于今后东北地区混凝土坝的建设技术改进 Some concrete dams in northeast China have undergone different degrees of weathering damage after decades or ten years of operation. Some have been unable to maintain their normal operation and have to undergo repairs such as plump dam, Yunfeng dam, Shenwo dam and so on. Investigate the destruction of these dams and explore the reasons for its destruction, to find its inherent regularity, for the future construction of concrete dams in Northeast improved technology
