湖南省设计洪水计算中的面积比拟法经验指数探讨

Study on Empirical Index n of Area Analogy Method in Design Flood Calculation in Hunan Province

在设计洪水计算中,当工程处没有水文资料时,广泛采用临近(上下游)水文站进行洪水频率计算,再用面积比法进行改正到工程处,湖南省广泛采用面积比的经验指数0.67次方进行改正。本文对0.67进行了探究,提出了新的改正指数,可供广大工程技术人员参考。

In the design flood calculation,when the engineering department has no hydrological data,the flood frequency meter is widely used near(upstream and downstream)hydrological stations.After calculation,the area ratio method is used to correct it to the engineering office.The empirical index of area ratio is widely used to correct it to the power of 0.67 in Hunan Province.This article on 0.67,and put,forward a new correction index,which can be used as a reference for the majority of engineers and technicians.
