国产道岔区无砟轨道结构设计研究

Research on Ballastless Track Structural Design in Domestic Turnout Area

介绍了国内外岔区长枕埋入式和岔区博格板式无砟轨道的结构设计情况,对国产道岔区轨枕埋入式无砟轨道的结构进行研究,提出道岔区轨枕埋入式无砟轨道设计主要应解决道床板分段长度的确定、转辙机区域细部设计、道岔区为确保施工"零位移"的加固措施及岔区排水设计等几个关键技术。

This paper introduces the structural design of monoblock and boegl plate ballastless track in turnout area at home and abroad, then conducts a research on the structure of monoblock ballastless track of domestic turnouts and proposes that the design should focus on such key techniques as determination of the section length, detail design of the point machine area, fixing measures to guarantee zero displacement and drainage design in turnout area.
