时速350公里高速铁路CRTSⅡ型板式无砟轨道箱梁梁面平整度控制技术

Control Technique for Flatness of Top of Box Girder of Model CRTSⅡ Plate-type Ballastless Track for Passenger Railway Line with the Design Speed of 350 km/h

CRTSⅡ型板式无砟轨道技术对桥面平整度要求非常严格,通过对京石铁路客运专线滹沱河制梁场桥面平整度控制的具体措施的论述,为推广CRTSⅡ型板式无砟轨道技术,减少梁面打磨工作量提供参考。

The technology of model CRTSⅡplate-type ballastless track has a very high demand on the flatness of bridge deck.This paper expatiates and discusses specific measures for control of the flatness of bridge deck of Hutuo River prefabricating girders plant of Beijing-Shijiazhuang Passenger Railway Line,so as to supply references for spreading of the technology of model CRTSⅡplate-type ballastless track and reducing workload of polishing top of girders.
