摘    要:坝陵河特大桥位于地形特殊的山区,桥址风环境非常复杂,是我国西部山区桥址的典型代表,为了正反映桥址处风的实际状况,探索通过地形模拟风洞试验来确定桥梁设计基准风速和相关的风特性参数的方法和可靠性,为将来类似桥梁提供参考.试验研究结果表明:坝陵河特大桥在横桥向来流作用下,跨中桥面高度处风速受到“峡管效应”的增速作用;峡谷内平...

关 键 词:桥梁工程  风场  地形风洞试验  山区峡谷  桥址  风荷载

Abstract:Baling river grand bridge is located in special mountainous area with very complicated wind field which is the representative case in west China.The particular terrain model,which can simulate the practical status of wind field in bridge site,was tested in wind tunnel to confirm the design norm wind speed and the related wind characteristic parameters to give reference to future similar bridge designation,and the test method was researched to identify the correctness and reliability at the same time.The tes...
