地铁线路CPⅢ轨道控制网的应用

Application of CPⅢ Track Control Network in Metro Line

目前CPⅢ轨道控制网(以下简称CPⅢ网)主要运用于高速铁路及客运专线,近年来,部分城市新建城市轨道交通(地铁)线路也逐渐推广应用CPⅢ网,从而使轨道施工精度得到了很大提升,同时对开通后的运营维护起到了关键指导作用。下面就城市轨道交通(地铁)线路CPⅢ网的应用情况进行简单分析总结。

At present, CPⅢ track control network （hereinafter referred to as CPⅢ network） is mainly used in high-speed rail-ways and passenger dedicated lines. In recent years, some new urban rail transit （subway） lines in cities have gradually popularizedand applied CPⅢ network. Thus the precision of the track construction has been greatly improved, and the operation and mainte-nance of the track has playeda key guiding role. The following is a brief analysis of the application of CPⅢ network in urban railtransit （metro） lines, which is summarized as follows in the paper.
