摘要

与常见的单幅桥面桥梁相比，双幅桥面桥梁主梁断面的气动选型更为严格，必须同时保证上下游两主梁断面都具有良好的气动性能。以某在建的双幅桥面桥梁为背景，通过一系列节段模型风洞试验，从主梁断面基本形状和检修车轨道的位置及高度两个方面进行了主梁断面的气动方案比选，对双幅桥面桥梁主梁断面的气动选型进行了初步研究。

Abstract

Compared with common single deck bridge, the cross section aerodynamic optimization of twin deck bridge girder is stricter because the aerodynamic performance of both forward girder and leeward girder should be good at the same time. Based on a twin deck bridge which is under construction, a serial of wind tunnel tests of the sectional models were performed to get the best girder cross section through aerodynamic optimization of basic shape of girder cross section, position and height of repair-vehicle rail. This start a preliminary study on cross section aerodynamic optimization of twin deck bridge girder.
