轨道交通线路设计质量控制要点探析

A Study on the Key Quality Control Points in Rail Transit Route Design

轨道交通线路设计质量直接影响工程项目总体规模、运营效率及工程投资。为此,以工程案例为背景,在阐述线路设计技术标准的选取、线站位研究、敷设方式、平纵断面技术条件、配线设置、交通衔接和疏解、与交叉衔接线路关系、环境及文物保护等轨道交通线路设计质量控制要点的基础上,从合规性、合理性、安全可靠性、适应性、经济性等方面对线路进行全方位的质量控制和优化,提出线路设计的基本思路,为线路设计及优化,以及轨道交通的建设、设计、施工提供借鉴。

The quality of rail transit route design has an immediate influence on the overall project scale, operation efficiency and investment. This paper studies the key quality control points of several rail transit route design projects in eight aspects： the technical standards of route designing, routes and station locations, the laying methods, the technical conditions of cross and vertical sections, the wiring system, traffic connection and dispersion, the relation to the connected intersectional lines and protection of the environment and cultural relics. In order to achieve the optimized route design, this paper puts forward the basic ideas in optimizing route design with comprehensive quality control from the following perspectives： conformity, reasonability, security, reliability, adaptability and economy, and these are expected to have practical values in development, design and construction of rail transit projects.
