同频率地区组成法在洪水计算中的应用

Application of the Region Composition Method of the Same Frequency in Flood Calculation

随着人类治水力度的不断加大,河道上的水库工程越来越多,水库建成后,会对下游工程的设计洪水产生较大影响,文中采用同频率地区组成法计算了受郭堡水库影响的象峪河桥设计断面洪峰流量,为象峪河桥拆除重建工程设计提供了依据,对同类型工程洪水的计算有一定的借鉴意义。

With the increasing of human efforts to control water,more and more reservoir projects on the river course will be built. After the completion of the reservoir,the design flood of the downstream project will be greatly affected. In this paper, the peak flow of the design section of the Xiangyu River Bridge affected by the Guobao Reservoir was calculated by the region composition method of the same frequency, which provides basis for the design of the demolition and reconstruction of Xiangyu River Bridge. The results could provide reference for projects of the same type.
