金华至建德高速铁路铺轨基地选址研究

Study on site selection of track laying base for Jinhua-Jiande high speed railway

铁路铺轨基地选址是一项关系全局的总体性工作。高速铁路因接轨站基本也是不办理货运的高速站或城际站,且线路区间桥隧比例高,铺轨基地岔线接入困难,因此,高速铁路铺轨基地选址较普速铁路难度更大。研究了金华至建德高速铁路铺轨基地选址,从工程、施工组织设计、既有线运营、安全等方面对不同方案进行了比较分析,提出推荐方案。文中研究思路、方法、过程及结论对相关高速铁路铺轨基地选址设计具有一定的借鉴意义。

The site selection of railway track laying base is an integrated work that has effect to the whole project.Because high-speed railway is basically high-speed station or intercity station which does not handle freight,and the proportion of bridge and tunnel is high in the line section,it is difficult to access the bifurcated line of track-laying base.Therefore,it is more difficult to locate the track-laying base of high-speed railway than that of general speed railway.This paper studies the site selection of Jinhua-Jiande high-speed railway track laying base.By comparing engineering,construction organization design,existing line operation and safety of different schemes,we put forward the recommended scheme.The research idea,method,process and conclusion of this paper have certain reference significance to the site selection design of the relevant high-speed railway track-laying base.
