摘要
在现代城市桥梁工程中,特别是在城市立交枢纽工程、城市高架桥工程中,考虑桥下地面交通、管线及美观等因素,常常不可避免地要用到大跨度小半径弯桥。成都"两快两射两环"项目中南二环上采用了这种大跨度小半径弯桥,采用Midas Civil 2010有限元软件,用单梁单元模型和梁格法分别对其进行了计算,通过对比分析了解了其结构受力行为。
In the modern urban bridge projects,especially the urban interchange projects and the urban viaduct projects,the long-span curved bridge with the small radius is often inevitably used by considering the transportation under bridges,pipelines and aesthetic factors. This kind of long-span curved bridge with small radius was used on the south second ring road in Chengdu of the project of＂Two expressways,Two extended roads,Two ring roads＂. It was calculated by using the finite element software of Midas Civil 2010 with the beam element model method and the grillage method. After comparing the results,the force of the structure was obtained.
