Paper Abstract

In this paper we present an engineering application of optical fiber distributed sensing for monitoring of the ground settlement during a tunnel excavation. The design, installation methods, and implementation of 4D (space plus time) warning system are outlined. The ground settlement was closely monitored for entire 6 months of tunnel construction process, revealing a wide range of geomechanical phenomena. Obtained on-line vertical displacements allowed engineers to control the excavation speed and monitor ground settlement, contributing substantially to the overall reliability and safety.
