Abstract

It is of significance for Tunnel Boring Machine (TBM) to conduct rock-breaking efficiently and rapidly throughout tunnel construction. The efficient rock-breaking mechanism of TBM has always been a hot yet tough issue in geotechnical engineering. In this paper, by using a self-developed large experiment platform, rock-breaking experiments are conducted with a varying number of disc cutters from one to three. The failure processes of red sandstone, limestone, and granite, are illustrated. The optimal cutter spacing of them is generalized. For further, a formula of wide applicability on optimal cutter spacing is proposed in case the rock's uniaxial strength ranges from 40~170MPa.
