摘　　要：黑龙江流域因冰冻时间长,流冰撞击力巨大,水域可施工周期短的特点,常规水上施工栈桥架设钢桁梁方案危险系数大,一次投入大,施工周期长。利用起重机驳船组合设备膺架以及进行钢桁梁架设施工是一种既安全可靠又可以大大缩短工期的施工技术。本文以新建同江中俄铁路大桥144m跨钢桁梁架设为例重点介绍大临施工、吊机上船、钢桁梁架设等施工技术。Due to the characteristics of long freezing time,huge impact force of flowing ice and short construction period of water area in heilongjiang river basin,the steel girder erection scheme of conventional overwater construction trestle has high risk factor,large one-time investment and long construction period.It is a safe and reliable construction technique to use crane barge assembly equipment and steel girder erection.Taking the erection of 144m steel girder of the newly-built Tongjiang china-russia railway bridge as an example,this paper mainly introduces the construction techniques of dalianconstruction,crane boarding and erection of steel girder。
