Abstract: Based on engineering characteristics of the high dam group in Yalong river basin, this paper points out these key issues in operation safety as well as main technical issues need to be solved in operation period, such as the operation safety of over-flow structures in complex conditions and the application of dynamic diagnosis and geophysical detection technology. Further, the management trend of dam safety is also discussed, resulted in a new direction of development, namely the risk management and the digitized dam safety management.

摘要： 针对雅砻江流域高坝群的工程特点，对其运行安全关键问题进行梳理，指出了运行期需要解决的关键技术问题，如复杂环境下的过水建筑物运行安全、动力诊断与物探检测技术的综合应用等；并对流域大坝安全管理的发展趋势进行了探讨，提出了向以风险管理为主的大坝安全管理新模式转变、向数字化大坝安全管理转变等新的发展方向。
