摘要
尼铁现代化铁路项目是尼日利亚国家铁路重点建设项目,其中Oshogbo至Gwada段河流水系发达,河流纵横。影响河流设计暴雨洪峰流量的自然地理因素较多,归纳起来主要有气候、暴雨、土质、土壤、植被及地形。该文详细介绍分析各自然地理单项因素的特征及其对河流暴雨洪峰流量的影响,总结沿线河流暴雨洪峰流量的特征、设计暴雨洪峰流量计算参数的计算方法及其取值。
Nigeria Modernized Railway Project is the key construction project of Nigeria railway. In the section from Oshogbo to Gwada, the water system of the rivers is flourishing and the rivers are in length and breadth. There are many natural geographic factors to influence the design rainstorm flood peak flow of the rivers. The collected factors are mainly the climate, rainstorm, soil, vegetation and terrain. The article introduces and analyzes in detail the characters of every single factor of the natural geography and its influence on the rainstorm flood peak flow of rivers, sums up the characters of rainstorm flood peak flow of the rivers along the railway, and its calculation parameter method and its data of the design rainstorm flood peak flow.
