Tunnel Detection Equipment and Recognition Method Discussion and Prospects

Abstract

Traffic construction has always been an important prerequisite to achieve China's economic development and social progress. In a country with rich landforms, mountains and hills account for about 67% of the land area, tunnels play a positive role in improving transportation efficiency and alleviating urban traffic pressure, and the diagnosis and treatment of lining diseases is the primary task to ensure the safe operation of tunnels. In this paper, the development status of lining disease identification criteria, identification technology and identification integrated equipment are elaborated and analyzed in detail, and the treatment of lining disease is briefly discussed. The main conclusions of this paper are as follows: 1. All countries have relevant provisions on the judgment and management of tunnel safety, and the safety classification of tunnels has been basically defined. 2. In view of different disease characteristics of tunnels, the integration of multiple detection technologies is the mainstream trend at present. 3. The development of lining disease detection technology and methods has been relatively perfect, and major countries have mature commercial products for tunnel safety hidden danger detection.
