Abstract: Dam safety emergency plan is an important non-engineering measure to reduce loss. Taking a concrete double-curvature arch dam as an example, combined with structures, operation characteristics and environment conditions, this paper analyses the emergency issues that may exert impact on dam safety, for reference.

摘要： 大坝运行安全应急预案是保障水库大坝遭遇突发事件时能有效减损的一项重要非工程措施。以某混凝土双曲拱坝为例，结合工程结构、运行特点和环境条件，对可能影响大坝安全运行的突发事件进行了详细分析，可供类似工程编制应急预案时参考。
