摘　　要：为解决“西气东输”管道大跨越可能造成的管道的较大变形对管线的不利影响 ,对宁夏中卫县CA10 5～CA10 6之间跨越冲沟的管道桥 (架 )进行了多方案的技术经济分析比较 ,计算表明钢结构拱桥较其他结构形式更为经济合理 ,并介绍了该钢结构拱桥的设计计算 。In order to eliminate unfavorable effect of larger deformation of pipeline by its long crossover for the projects of transporting gas to the East from the West,the schemes of the crossovers of CA105～CA106 in Zhongwei County of Ningxia Hui Autonomous Region are analyzed and compared technically and economically,which indicates that the scheme of steel arched bridge is more economic and rational than those of other structural forms,thus saving large amount of funds for the project.
