Abstract

Abstract: Tunneling by TBM is a popular method in the construction of urban Metro, due to the small space it takes on the ground surface, no effect on ground traffic and little effect on surrounding environment. TBM is designed for tunneling in soft rock. Hard rock is unavoidable in complex urban area. Tunneling data are analyzed, experience is summarized and a suit of tunneling technology of TBM boring in hard rock stratum is made. Good effect has achieved, the wearing of cutting tools and the cost are reduced, and high construction efficiency is improved. The paper can provide reference for similar projects in the future.

Key words: tunnel boring machine, tunnel technology, hard rock, cutting tool
