| 摘 要： | 为解决在水文计算中,遇上下游控制节点间距离较长,当上游洪水坦化变形明显时,采用现行的同频率组成法,会出现不合理结果的问题,提出了直接利用上下游断面实测资料分析洪水的坦化衰减,再将上游来水系列扣除衰减影响,然后用同频率地区组成法进行计算,并以头屯河流域为例进行了验证,结果表明,加入洪水衰减项对同频率地区组成法进行改进是合理可行的。

| Abstract: | When hydrologic calculation is operated,there are longer distance of nodal paint in upstream and downstream and deformation of floodwater in upstream is significant,the same frequency composition method is applied,which would produce unreasonable results.In order to resolve the problem,the authers proposed to directly analyze the attenuation of floodwater with the data observed from cross section of upstream and downstream and to deduct the attenuation effect of upstream system,then to calculate it with the method of same frequency area composition,and taking Toutun river for example to test and verify it,the result indicated that is practicable the improvement of the same frequency area composition including flood attenuation. |
