摘要

Recent years have seen a move towards the adoption of mined tunnels to house urban infrastructure. Tunnels can meet a wide range of infrastructure needs, including those required for cable, pipeline, and transportation uses. In the congested city selecting an underground site can offer important aesthetic, construction and operational advantages to the infrastructure operator.Recent advances in tunneling technologies, notably in the areas of mechanical excavation (Tunnel Boring Machines, TBM) and ground control haverendered underground construction a technically feasible optionsat most sites. This paper discusses early value engineering proposals developed in the course of two studies to advance the efficiency of the TBM-system mining in competent rock masses.
