In this field trial, a new monitoring technique using distributed strain sensing known as Brillouin Optical Time Domain Reflectometry (BOTDR) was introduced to monitor the behavior of bolted-concrete linings of a recently completed tunnel when a second bored tunnel was constructed side by side at a...
