CPⅢ精测网及轨检小车在高速铁路养护中的应用

Applications of CPⅢ Precision Surveying Network and Track Inspection Trolley in the Maintenance of High Speed Railway

近年来,随着经济社会的发展,我国铁路运输事业快速发展,尤其是高速铁路快速发展,高铁总里程超过了2.5万km。由于高速铁路的运行速度非常快,在运行过程中会产生很大的摩擦力。为了确保高速铁路运行安全,日常工作中,必须加强对高速铁路的养护。本文简单阐述了高速铁路的特点以及高速铁路精测系统以及CPⅢ精测网和轨道检小车在高速铁路养护中的具体应用,希望为高速铁路的养护工作提供参考和借鉴。

In recent years,with the economic and social development,the railway transportation industry in China has developed rapidly,especially the high-speed railway,which has exceeded the total mileage of 25 000 kilometers. Since the high-speed railway runs very fast,it is subject to great frictions in the course of operation. In order to ensure the safe operation of high-speed railways,the maintenance of high-speed railways must be strengthened during the daily process. By describing the characteristics of high-speed railways,this paper expounds concrete applications of the CPⅢ precision surveying network and the track inspection car in the maintenance of high speed railways,in order to provide a reference for the high-speed railway maintenance work.
