高速公路桥涵水文的调查、分析、计算要求的是对通过各种途径和方法计算得到的结果进行比较、论证,确定设计流量,使其更接近于实际,更趋于合理。该文介绍了应用当地的规范、标准对东部非洲某国高速公路桥涵水文水力分析的过程、步骤、方法以及程序,为东非地区类似国家公路的水力水文分析提供参考。 Highway bridge and culvert hydrological survey, analysis, calculation requirements is calculated through a variety of ways and methods to compare, demonstrate, determine the design flow, so that it is closer to reality, more reasonable. This paper introduces the process, procedure, method and procedure of hydrological and hydrodynamic analysis of highway bridges and culverts of a country highway in East Africa by using local norms and standards. It provides a reference for hydro-hydrological analysis of similar countries in East Africa.
