摘　　要：本文通过柳州南编组站竹鹅溪多线刚构桥梁部现浇支架施工实例,介绍移动支架的设置组成,结构受力检算,施工方法、注意事项,预压方法。该施工方法,将传统工艺进行改进,施工方便,可减少支架地基处理数量、缩短工期、提高施工工效,解决了铁路站场横向宽度较大的刚构桥梁部支架现浇法施工的问题,取得的经验成果可为类似施工提供参考。Based on the construction example of cast-in-place supports of Zhu'exi multi-line rigid frame bridges in Liuzhou South Marshalling Station,this paper introduces the setting and composition of mobile supports,structural force checking,construction methods,precautions,and preloading methods.The construction method improves the traditional process,and the construction is convenient.It can reduce the number of support foundation treatments,shorten the construction period,and improve the construction work efficiency.The empirical results can provide reference for similar construction.
