大伙房水库上游区设计洪水复核

Design flood recheck in the upstream of Dahuofang Reservoir

2013年8月15日至17日,抚顺地区出现区域性大暴雨,致使浑河上游北口前站、四道河子站的洪峰流量超过了历史记录,给浑河原设计洪水成果提出重新复核计算的要求。根据本次暴雨洪水过程,结合对历史洪水调查以及历史洪水重现期的分析进行洪峰、洪量频率计算。结果表明,除暴雨中心附近的北口前、红河四道河子水文站设计洪水成果有所变化需要采用新成果外,其它站的设计洪水成果均没有变化或变化很小,因此可继续使用。

August 15,2013 to 17,in Fushun appear regional heavy rain, resulting in peak flow in the mouth of the former North Station and Sidaohezi station upstream Hun River is over the historical record;it requires recheck the original design flood result.The process according to the Storm and Flood combination of surveys and analysis of historical flood return period of historical floods were peak,magnanimity frequency calculation. The results showed that,in addition to heavy rain north exit near the center of the Red River Sidaohezi Hydrologic Station Design Flood vary require the use of stations did not change or changes very little, so it external new results, the results of the design flood of other can continue to use.
