摘　　要：忠武输气管道有4次悬索跨越,分别是蚂蝗溪悬索跨越、木龙河悬索跨越、马水河悬索跨越、野三河悬索跨越。文章介绍了这几座悬索跨越管桥设计中采用的多项新技术,如采用热聚乙烯半平行钢丝索代替以往的钢丝绳;采用钢管塔架代替以往的角钢塔架;根据地形地貌特点变换风索型式或取消塔架等。这些新技术、新设计在工程中均取得了良好的效果。另外,文章还针对悬索跨越桥面结构型式、预拱度设置、不对称荷载的影响、风索基础的设置等问题进行了探讨。This paper introduces some new techniques used in four suspension cable type pipeline bridges in Zhongxian-Wuhan Gas Transmission Pipeline Project, such as substituting thermo-polyethylene semi-parallel steel wire cable for former steel wire rope, substituting steel pipe tower for former angle iron tower, altering wind cable form or canceling tower according to topographic and physiognomic features. These new techniques and designs achieve good results in engineering projects. Furthermore the paper discusses the bridge structure form, precamber setup, asymmetric load influence and foundation setup of wind cables.
