Experimental Study on Strength and Deformation of Fiber Blended Drymix Mortar Sprayed in Order to Prevent a Rockfall...
Abstract: In this study, we sprayed a fiber blended drymix mortar, and a concrete with powdered or liquid accelerator to a rough plate of granite mounted on a punching experimental equipment. Those strength and deformation were measured and compared by its equipment with a three-dimensional laser scanner. As a result, the redundancy of the fiber blended drymix mortar sprayed was superior to that of the...

Reinforcement Measures for Tunnels with Large Deformation
Abstract: During excavation of the Matsukaya Tunnel in fragile pelitic schist, a horizontal displacement of up to 770 mm occurred on one sidewall, damaging the primary support and heaving the invert. To stabilize the tunnel during excavation and to prevent the deformation risk during service, the invert was reinforced with struts and the lining was fiber-reinforced. Moreover, a numerical analysis was...
