Abstract

Nowadays, the scale of cities continues to expand and rail transit is developing day by day. It is more and more important to ensure the efficient and safe operation of rail transit. As an important factor affecting the safe operation of subway lines, the profile of the tunnel section is constantly updated with the development of the line. Efficient, automated, and intelligent tunnel section detection new technology has become a research trend and hot spot. This paper analyzes the current situation of tunnel section detection technology in China and abroad. Introduced a metro tunnel section test technology based on 350 degree laser scanner. The system has the characteristics of digitalization, miniaturization, modularization, high integration and real-time. Apply the product to an existing subway line, analyze and process the obtained data, and obtain specific information about the intrusion limit hazard on the line, so as to verify the feasibility of the system.
