城轨交通车场线轨道结构的探讨

研究目的:为满足城轨交通运营的需要,必须设置车辆段与综合基地.在调查研究我国城轨交通工程已建成运营的车辆段与综合基地铺设的车场线路使用情况的基础上,依据不同的车场线路类型研究设计相应的轨道结构,并结合成熟的国铁设计理论和经验,对车场线路轨道结构进行优化.研究结论:试车线及其它库外线设置碎石道床可减振降噪,减小对周边环境的影响并能降低工程造价;库内线根据不同工艺要求设置立柱式和坑道式检查坑整体道床,可方便工艺操作,并可减少线路养护维修工作量.线路均采用弹性扣件,增强了轨道安全性及稳定性,取消了轨道加强设备,减小了养护维修工作量.同时合理的设置车场线路道口、车挡等轨道附属设备,可以更好的为运营服务.

Discussion on Yard Track Structure of Urban Mass Transit

Research purposes: Urban mass transit system has its depot and multi-purpose base.This paper researches the relative track structures for different types of yard tracks on the basis of investigation of applicable situations of yard tracks for some depots and integrated bases of urban mass transit in China and presents the optimum design of yard track structure on the basis of national railway theory and experience.Research conclusions:Ballast bed should be installed for the test track and track outside the ...
