大坝防洪安全评价中防洪专题的确定原则

Determination principles for the flood study in flood control safety assessment

防洪复核专题确立是大坝安全定检中十分重要的工作,在对以往防洪专题确定因素大量统计分析基础上,在《水电站大坝运行安全评价导则》中提出了防洪专题确定原则,给出背景成果。

Determination of flood study is of great importance in dam periodical inspection. Based on the statistics of determination factors in the past experience and combined with research results, the determi-nation principles were advanced in the Guide for safety assessment of hydropower dams in operation, for reference.
