The Role of Digital Monitoring Technologies in the Development of Comprehensive Tunnel Maintenance Strategies

摘要

Owners and operators of infrastructure such as railways, roads, subway systems and water supply systems are obliged to provide state-of-the-art, safe, dependable and economical services to their customers in an ever increasingly complex environment. One key aspect is the maintenance of tunnel infrastructure. The economic effectiveness of maintaining tunnel infrastructure can be increased through implementation of comprehensive maintenance strategies which utilize modern digital monitoring technologies. A wide range of digital monitoring technologies are currently available, two of which include tunnel mapping and tunnel scanning. Both of these technologies can be systematically applied within the framework of comprehensive long-term maintenance planning. This paper introduces tunnel mapping and tunnel scanning technology and provides insight into how these and other digital monitoring technologies may be successfully integrated into the development of comprehensive tunnel maintenance strategies.
