Overview of camera detection and laser scanning detection technology for subway tunnel structural diseases

Inhalt:
Subway plays a great role in urban public transportation because of its advantages of large capacity, fast and energy saving. Under the influence of the constant change of service environment and the gradual degradation of material performance, the damage caused by the degradation of subway tunnel structure performance is becoming increasingly prominent. The healthy service of subway tunnel is facing severe challenges, which directly affects the operation efficiency and public transport safety of Metro. How to complete a large number of detection work in a limited time has become the focus of the development of detection technology. In this context, the efficient and fast camera measurement and laser scanning measurement technology have become an important direction of the development of tunnel rapid detection technology. This paper will introduce the current research status of traditional detection methods, camera detection technology and laser scanning detection technology for typical structural diseases of tunnel environment, and summarize and prospect the rapid disease detection technology.
