The Application of Survey Technique to the CRTSII Ballastless Track of Static Adjustment

In order to adapt to the requirements of stability and comfort of high-speed railways,The track structure must has high precision of track laying,and even the precision is in degree of millimeter,so survey technique is very important.The ballastless track of static adjustment is the last Procedure of Long Rail static state adjustment technology and it is very important to the whole measuring process.In this paper,we study a case about SWZQ-7 bid section Super Major Bridge on Luo he-Zhu madian of Wuhan-Guangzhou Passenger Dedicated Line,analyzes and researches on CPⅢsurveying,setting station of total station instrument,field data collection and simulation to adjusting.The finel result shows the importance of surveying Technique in CRTSⅡ unballasted Track Long Rail static state adjustment.
