Abstract

Face bolting is one of the effective methods to stabilize tunnel face. This paper will describe that development of new type of face bolting using Glass Fiber Reinforced Plastic tube. Some drilling tests have been performed in various geological conditions, and have been evaluated drilling applicability.
Pull out tests have been also carried out to evaluate the bonding properties of GFRP face bolts.
