RAM analysis of earth pressure balance tunnel boring machines: A case study
Earth pressure balance tunnel boring machines (EPB-TBMs) are favorably applied in urban tunneling projects. Despite their numerous advantages, considerable delays and high maintenance cost are the main disadvantages these machines suffer from. Reliability, availability, and maintainability (RAM) analysis is a practical technique that uses failure and repair dataset obtained over a reasonable ti...

متن کاملA Machine Learning Approach to Predicting and Maximizing Penetration Rates in Earth Pressure Balance Tunnel Boring Machines
Modern tunneling projects will often rely on a Tunnel Boring Machines (TBMs) rather than traditional drill and blast (D&B) methods, because of TBMs’ increased tunneling efficiency[1]. TBMs have a circular drill at the front, which can range in diameter from 1 meter to 19.25 meters, depending on the desired use for the completed tunnel. Applications of tunnels dug by TBMs range from underground ...
متن کاملSimulation of tunnel boring machine utilization: A case study
Utilization is one of the main managerial factors that is applied for construction process analysis well. It directly affects the project duration and construction costs. Therefore, a utilization study in tunneling projects is essential. 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 simula...
متن کاملthe reliability of a tunnel boring machine
greater levels of complexity in tunnelling with tunnel boring machine (tbm) allow higher chances of failures that may increase the potential hazardous risks. this paper presents the results of a study on tbm reliability using risk analysis. machinery failure mode and effect analysis was applied to analyze the risks of a tbm using qs9000 and sae.j1739 recommendations. for this purpose, 48 failur...
