Abstract：Research purposes: During the operation of high-speed railway, it is necessary to carry out periodic and random track detection and foundation deformation measurement in order to evaluate and grasp the stable and safe state of the line at any time. It is an important part of high-speed railway transport control system. In the field of high-speed railway, opinions on the measurement method, measurement accuracy and evaluation index of track are not consistent all the time, and there are many research projects on track measurement equipment and data processing in the industry. In this paper, the linear properties, linear composition and expression, and the derivation of measurement accuracy of the track are discussed, and the principle and method of using track alignment detection data are presented. Research conclusions: (1) The manifestation, observation method and disease degree control index of foundation deformation are studied, and the principle of "moving inspection as the main and static inspection as the repair" is put forward. On the premise of satisfying the accuracy and range of track control network required by track maintenance, the track control network retest and track static inspection are carried out. (2) The measuring datum of linear coordinate points in orbit space is the track control network with internal and external precision meeting the requirements, and the starting datum can be coordinate control or scale datum + direction datum combined control. (3) To determine the scheme and timing of maintenance of track and infrastructure, it is necessary to reasonably analyze and weigh the degree of impact and primary and secondary factors of high-speed railway lines. (4) The research results have a reference for the track detection and maintenance work.
