有砟客运专线CPⅢ控制网测量方法与实践

The CPⅢ Control Network Mehtod and Practice in Ballasted Track of Passenger Special Lines

有砟客运专线的列车运营速度较一般列车快,对轨道的平顺度要求较高,借鉴无砟客运专线CPⅢ控制测量技术对有砟客运专线进行CPⅢ控制网测量。以胶济铁路为例,详细论述平面控制测量、高程控制测量和数据处理方法,实践验证该方法可行,能够为类似工程提供借鉴。

The train of Ballasted track passenger dedicated line always run faster than general train,thus the demand to the smooth degree of track is higher.This paper takes Jiaoji railway as an example, described the CPⅢ control with reference on the CPⅢ control technology of Ballasted track passenger dedicated line,in detail elaborated the plane control survey,elevation control survey and data processing method,through practice verification the method is feasible and can be used for reference in the similar projects.
