山区高速公路大桥水文计算分析

Analysis on Hydrological Computation of Expressway Bridge in Mountain Area

以广西荔浦至玉林的高速公路为工程背景,根据当地历年水文观测数据,进行了南流江大桥的相关水文计算,包括设计洪水水位、水量、桥面最低设计高程、桥梁最小净跨径和墩台最低冲刷线标高等数据验算,为类似工程提供参考。

Taking the Guangxi Zhapu-Yulin Expressway as the engineering background and according to the local hydrological observation data over the years, the related hydrological calculations for the Nanliu River Bridge are performed including the data checking computation of design flood level, the water flow,the minimum design elevation of bridge deck, the minimum clear span of bridge, and the lowest scour line of piers and abutments. These analysis results provide a reference for the similar projects.
