安九高速铁路庐山站接触网改造及过渡设计研究

A Study on Renovation and Transition Design of Overhead Contact System in Lushan Station of Anqing-Jiujiang High-speed Railway

随着我国高速铁路的发展,新建高速铁路引入既有车站改造也越来越多,站房改造也倾向于采用高架站房方案。安九高速铁路引入既有庐山站,站场规模为8台25线,高速铁路场与普速铁路场并站布置,站内设计大型高架站房,并需对既有雨棚进行改造。高架站房及既有雨棚情况复杂,对接触网改造设计提出了更高的要求。通过综合考虑高架站房及既有雨棚的结构形式,提出了既有车站接触网改造及过渡方案,以及适应于庐山站的接触网方案,取得了良好的效果。研究成果对今后类似工程有一定的参考意义。

With the development of high-speed railways in China,new high-speed railways are increasingly being connected to existing stations,necessitating the renovation of existing stations,where elevated station buildings are preferred.Anqing-Jiujiang High-speed Railway is connected to the existing Lushan Station,with a station scale of 8 platforms,25 tracks,and the high-speed railway yard arranged side by side with the conventional speed railway yard.The station is designed with large-scale elevated station buildings and existing canopies need to be renovated.The conditions of the elevated station building and existing canopies are complex,putting forward higher requirements for the renovation design of the overhead contact system.By considering the structural form of the elevated station building and the existing canopies,a specific scheme for the renovation and transition of the existing station’s overhead contact system was proposed.This scheme is suitable for Lushan Station,and has achieved excellent results.The results of this study provide certain reference significance for similar projects in the future.
