摘要
在水文分析计算中,设计洪水过程线是水利工程防护安全的重要依据,在因采用的方法不同,所涉及的洪水过程线的方法也有较大的差异,也影响到防洪工程的设计指标,本文通过实例就水文设计规范中常用的同倍比放大法和同频率放大法[1]两种放大方法进行比较,分析其优、缺点和适用性,以便在实际中具体应用。
In the hydrological calculation,design flood hydrograph is an important basis for safe water conser-vancy protection,due to the different methods used in flood hydrograph methods,involved are also great differ-ences,which also affect the design specifications flood control projects.This article,taking an example of engi-neering practices,carried out comparison between usual amplification method and the same frequency amplifi-cation method in the hydrologic design specifications.It analyze the advantages and disadvantages and appli-cability to the specific application in practice.
