西安地铁2号线轨道系统设计思路及创新

摘要

在分析西安地铁线网及2号线轨道系统特点和技术要求的基础上,对轨道系统的设计思路及实践,轨道系统在轨底坡参数、扣件、应对地裂缝轨道结构、地铁专用预应力混凝土岔枕及浮置板技术要求等方面的创新成果进行了总结,以指导西安地铁线网其它工程轨道系统的设计,也可为其它城市地铁轨道系统设计提供参考.%Based on the characteristics of Xi'an metro net works and the track system of metro Line 2, this paper discusses the design concept and practice, rail base slope and fastener, methods for dealing with the ground fissure structure, application of specialized pre-concrete switch sleepers and floating slab system, in order to guide the track system design of Xi'an metro lines and make this research as a reference for urban rail transit track system.
