复杂环境下穿铁路特殊框架桥施工技术分析

Analysis on Construction Technology of Railway Special Frame Bridge in Complex Environment

以京哈下行线铁路滦县车站站内复杂环境下穿铁路超大长宽比框架桥的工程实例,结合其框架桥大孔、长宽比大、顶进距离长等复杂的施工环境,进行超大长宽比框架桥的顶进施工技术的研究。

Based on the engineering example of the large length-width ratio frame bridge in the complex environment of luanxian station of Beijing-Harbin downline railway,this paper studies the jacking construction technology of the large length-width ratio frame bridge in combination with the complex construction environment such as large hole,large length-width ratio and long jacking distance.
