高铁与在建铁路并行段线路方案比选研究

Research on the Comparison of High-speed Railway and Under Construction Railway Parallel Section Scheme

当高铁与在建铁路并行时,并行段线路方案的选择和建设方案的确定直接影响到铁路施工安全和工程的经济性,如何在有效确保施工安全的同时缩短线间距、节约用地和减少拆迁量,提高工程经济性是高铁选线设计研究的重点内容。论文以南沿江城际铁路为项目背景,对高铁与在建铁路并行段选线要点和建设方案进行总结和研究,从而对高铁与在建铁路并行段的选线设计提供借鉴和参考。

When the high-speed railway and the railway under construction in parallel, the choice of its parallel section of the program and the consuction program to determine a direct impact on the safety of railway construction and engineering economy, how to effectively ensure the construction safety line spacing,increasing the project economy is the key content o fthe high-speed railway line design. This paper summarizes and analyzes the main points and construction schemes of high-speed railway and parallel railway line under construction, and provides some reference and reference for high-speed railway and the parallel section of railway under construction.
