Sensing solutions for assessing and monitoring tunnels

N.A. Hoult,    Queen’s University, Canada

K. Soga,    University of Cambridge, UK

Abstract:

This chapter introduces the most common sensors used for the monitoring of tunnels. It is divided into sections that cover typical tunnel monitoring applications: (i) construction in soft ground; (ii) construction in rock; and (iii) in-service and long-term monitoring. A case study is used for each application to illustrate the use of both common and newly developed sensing technologies in tunnel monitoring. The chapter concludes with a summary of the sensors discussed, future trends in sensing for tunnels and useful references.
