小流域暴雨洪峰流量,是铁路、公路等工程设计中确定桥涵孔径大小的基本数据。这篇文章主要介绍铁道部第一设计院等三个单位在无产阶级文化大革命中坚持开门办科研,深入勘测现场,开展了对洪峰流量计算方法的研究,提出了符合我国实际情况的小流域暴雨洪峰流量的计算方法。 全文计四部分:一、暴雨洪峰计算流量的形式;二、小流域暴雨洪峰流量形成的主要因素简介;三、小流域暴雨洪峰流量公式的推导;四、算例。本刊上一期已登出前两部分,这一期继续刊出第三、四部分,供读者参考。
Small watershed storm peak flow, is the railway, highway and other engineering design to determine the basic data of the size of the bridge and culvert. This article mainly introduces three units, including the First Design Institute of the Ministry of Railways, insisting on opening a door for scientific research during the Great Proletarian Cultural Revolution, conducting in-depth investigation of the site, carrying out a study on the calculation method of peak flow, and proposing a rainstorm in small watershed that is in line with China’s actual conditions Peak flow calculation method. The full text consists of four parts: First, the storm flood peak calculated in the form of flow; Second, small watershed storm flood peak flow formation of the main factors; Third, the small watershed storm flood peak flow formula derivation; Fourth, an example. The first issue of this issue has been out of the first two parts, this issue continues to publish the third and fourth part, for readers reference.
