无资料地区五台子水库防洪标准复核计算

五台子水库运行多年，出现部分工程老化等诸多病险隐患，水库除险加固设计的关键就是防洪标准复核。水库所在河流无水文资料，为此采用无资料地区设计暴雨洪水计算方法，对不同频率设计暴雨、设计洪水进行了复核计算与分析，复核后五台子水库的防洪标准为10年一遇设计，20年一遇校核。通过对防洪标准复核为水库下一步做好除险加固和工程运行管理提供依据。

Review of flood control standard in Wutaizi reservoir where no previous data exists

The Wutaizi reserxoir has been in work for years,parts of the reserxoir due to aging factors haxe many hidden hazards,and the key to its rehabilitation design is the rexiew of flood control standard. The rixer which the reserxoir is loca-ted at has no existing hydrologic data,hence the designed storm/flood calculation method which suits for region without data is used to rexiew and analyze designed storm and flood with different frequency. After rexiewing the flood control standard of Wutaizi reserxoir is designed by once exery 10 years and rechecked once exery 20 years. The rexiew is of great support for reinforcing process and engineering operation.
