Tunnels

Tunnels

Monitoring of tunnels encompasses the strength of the tunnel structure and the ground surrounding it. Ground deformation monitoring in tunnels assists in selection of suitable support mechanisms during excavation and produces an early warning framework to prevent structural damage or ground collapse.  Safety is a critical factor, so selecting the right monitoring instrumentation is vital in accident prevention and project security.

Geotechnical instrumentation is used to monitor ground deformations, typically extensometers, inclinometers and piezometers. Additional instrumentation can be used to measure tunnel profile, such as the Shape Accel Array.
