新建吉布提铁路工程 Galile ～Nagad水文分析与研究

摘要

The hydrological data and meteorological data of Djibouti are limited,and there is no relevant hydrological cal-culation method.Through analyzing the adjacent countries which have similar rainfall characteristics and geographical loca-tions and referring to the hydrology calculation method of domestic environment,small watershed model was established in accordance with the observations of rainfall.By using curve fitting,the discharge formula suited for the Galile ~Nagad sec-tion of Djibouti railway was achieved.The work of hydrology calculations for small bridge and culvert along the railway was completed successfully by means of the formula.%吉布提当地水文资料，气象资料数据有限，并且没有相关水文计算方法。通过分析地域相近、降水特点类似的非洲国家水文计算方法，同时借鉴国内类似环境水文计算方法，结合实际观测资料，建立小流域模型，经过曲线拟合，得到适应吉布提铁路 Galile ～Nagad 段沿线流模计算公式，圆满地完成了铁路沿线小桥涵水文计算工作。
