摘　　要：既有铁路车站的升级改造工程中,不少车站需要增加跨线人行天桥。此文介绍了已经开通运营的包西铁路通道东胜西站增加架设跨线人行天桥工程项目的施工经验。文章从吊车的选用和占位、天桥吊点位置的确定、吊耳的尺寸和构造、钢丝绳和卡环的选用、天桥吊装的施工方法等一一进行了介绍,可为同类工程借鉴。Rail-crossing overpasses are built in many renovation projects of existing railway stations.In this article we introduced the experience of installing steel truss overpass at the Dongsheng East Station of BaoXi Railway.We discussed many aspects of details in the construction,including crane options and locations,lifting points of overpass,lifting ear’s size and structure,options of wire ropes and snap rings,and method of hoisting construction.We believe these experiences will prove helpful in the construction of similar projects in the future.

关 键 词：既有铁路升级改造工程 车站人行天桥架设 钢桁架天桥吊装施工技术
