福州南江滨东大道下穿福厦高铁设计与施工要点分析

Analysis on design and construction essentials when Fuzhou south riverside east road cross below the existing Fuxia high-speed railway node

随着市政路网与铁路网密度不断攀升,交通通道资源愈发紧缺,不同交通方式间的穿越交叉逐渐增多。文章以福州市南江滨东大道下穿既有福厦高铁为案例,分析与探讨市政道路建设对既有高速铁路的影响因素,从道路线位、跨越结构形式、市政管线、临近石方爆破工艺等设计与施工要点方面提出了一套削减影响的技术方案。

With the continuous promotion of the density of municipal road and railway networks,traffic channel resources are increasingly scarce and the cross has gradually increased in diffent transportions. In this paper,taking Fuzhou south riverside east road corssing below Fuxia high-speed railway as a case,the influence factors of municipal road construction on existing high-speed rail were analysised and discussed,and put forward a set of technical methods to reduce the influence from the design and construction essentials of road route,crossing structure form,municipal pipeline,and blasting technology for adjacent stonework,etc.
