A STUDY OF CONSTRUCTION EXECUTION OF PERMEABLE SLAG ROADBED FOR RAILWAY TUNNEL

Abstract

The permeable roadbed using the slug materials is adopted in the tunnel under the Shirasu ground water level on the Kyushu Shincansen started in March, 2004. The purpose of permeable roadbed is decline of ground water level and prevention against the mud-pumping of Shirasu by trainload.
