广深准高速线路有关技术参数的追踪调查研究

Follow-up investigation and research on railway design & track maintenance main parameters for Guangshen quasi high-speed line

主要以客、货共线的广深准高速铁路养护维修作为实例，在广泛收集和吸收国内外的铁路理论以及试验成果的基础上，论证了目前广深准高速铁路平、纵断面的设计参数和轨道结构的合理性，提出了供其它线路进行准高速技改参考的设计参数和轨道维修技术参数。

Refering to the experiences of Guangshen quasi high speed mixed line, on the basis of widely collecting and digesting railway theories and testing results from home and abroad, this article demonstrates the rationality of railway design & track maintenance main parameters in Guangshen quasi high speed line,and then puts forward the proposal parameters which may be used for upgrading other existing lines.
