Early Evaluation of Ground Conditions ahead of Tunnel Face by Inclination Monitoring during Excavation
Available to Purchase
Paper presented at the 13th ISRM International Congress of Rock Mechanics, May 10–13, 2015
Paper Number: ISRM-13CONGRESS-2015-260
... by the electro-optical distance meter. Then, we have proposed a method that uses tilt sensors installed at the tunnel crown near the face to obtain the slight tilting information. To measure inclination of the tunnel crown, this inclinometer was originally developed as a daily management measurement...
