Abstract

The performance of the cable bolting system pre-installed in the pilot tunnel has been investigated. From the measurement results following two facts were clarified. 1) There was the generation of the axial force in cable bolts and they contributed to the stabilization of the face in the main tunnel. 2) It was possible to use the cable bolting system as a supporting member in the main tunnel.
