Global Tunnel Boring Machine (TBM) Market 2020 by

A tunnel boring machine (TBM) is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for micro tunneling. In Japan and China, The machine is used for soil are called shield tunneling machines and machines used for hard rock are called tunnel boring machine.

Forecasting of TBM advance rate in hard rock

2019-12-10  The efficiency of tunnel boring machine (TBM) is regarded as a key factor in successfully undertaking any mechanical tunneling project. In fact, an accurate forecasting of TBM performance, especially in a specified rock mass condition, can minimize capital costs and scheduling for tunnel excavation. This study puts an effort to propose two accurate and practical predictive models of TBM
