Simulation of the Construction of a Tunnel with a Tunnel ...

Construction of a tunnel with a tunnel boring machine (TBM) is usually a long-lasting project with complex interdependent processes and a comprehensive supply chain. Monetary losses due to equipment breakdowns and insufficient supply chains can range around 20% of the whole project cost, and that often means millions of dollars.

Simulation of tunnel boring machine utilization: A case study

In this work, the utilization of an earth pressure balance Tunnel Boring Machine (TBM) in Tabriz urban railway project was studied using the Monte Carlo simulation approach. For this purpose, the unit operation during one working shift such as boring time, ring building time, and locomotive travel time was recorded and saved in data base.
