桥梁辅通航孔施工方案比较研究

Comparative Study on Construction Schemes for Bridge Auxiliary Navigation Holes

文章以广西某桥梁工程项目为例,对其主桥辅通航孔进行了"挂篮悬臂浇筑方案"和"钢斜撑预制组拼顶推方案"的施工方案比较分析,从施工成本、工期及特点三方面探讨了两者的优缺点,分析结果可为今后类似桥梁施工提供参考。

With a bridge project in Guangxi as the example,this article conducts a comparative analysis on the construction schemes of the“hanging-basket cantilever casting scheme”and the“steel diagonal bracing precast group jacking scheme”for the auxiliary navigation hole of main bridge,then,from the perspectives of construction cost,construction period and characteristics,it discusses the advantages and disadvantages of theses two schemes,and the analysis results can provide reference for similar bridge construction in the future.
