Abstract: One of the key factors to ensure the construction quality of high-speed railways is the engineering project measurement technology. Engineering project measurement technology directly affects the normal operation of the train on the track. At present, there is still a certain gap in the construction of high-speed railway engineering projects in China compared with foreign countries. The systematic measurement theory and measurement technology of high-speed railway engineering still need to be improved. Corresponding technical difficulties often appear in highspeed railway engineering surveys. Based on the current development in the field of high-speed railway engineering survey in China, it is necessary to strengthen the research on the measurement technology, and on the basis of systematic research on the measurement technology, ensure that the train runs smoothly and safely on the track.
