ABSTRACT: An experimental application of a distributed optical strain sensing technique is presented with forepole support members of the umbrella arch tunnel support system. A laboratory testing scheme was conducted to verify the capability of the optical technique to capture expected support behaviour throughout all stages of construction as well as to demonstrate the potential to be used a novel geotechnical tool for optimizing support design in response to future ground conditions.
RÉSUMÉ: Une application expérimentale d'une technique de détection optique des déformations distribuées est présentée avec les du système de soutien de tunnel en arche de type parapluie. Un programme en laboratoire a été mené afin de vérifier la capacité de la technique optique à capturer le comportement du soutien attendu à toutes les étapes de la construction, ainsi que pour démontrer le potentiel optimiser la conception de soutien en réponse aux futures conditions du sol.
