摘　　要：石太线简子沟西人行道口改造工程,为三跨(15+20+16)m人行钢结构天桥。桥梁架设受铁路运输生产、电化挂网、场地条件等各种因素的影响较大,通过现场调查,决定利用既有小区平台、采用400t汽车吊,距离既有挡墙边4.0m设置吊车站位的吊梁方案,并检算挡墙稳定性满足要求,从而解决了山区铁路平改立大吨位机械作业的问题,对类似工程具有一定借鉴和指导意义。The reconstruction project of the Jianzigou West Sidewalk in Shitai Line is a three-span(15+20+16)m pedestrian steel structure flyover.Bridge erection is affected by various factors such as railway transportation production,electrified hanging network,site conditions,etc.Through on-site investigation,it is decided to use the existing residential platform,400t car crane,set beam lifting plan at 4.0m from the existing retaining wall,and check the stability of the retaining wall to meet the requirements,thus solving the problem of the large-tonnage mechanical operation of the mountain railway,which has certain reference and guiding significance for similar projects.
