Performance Prediction of a Hard Rock TBM using Statistical and Artificial Intelligence Methods

Alireza Afradi; Arash Ebrahimabadi; Mansour Hedayatzadeh

Volume 15, Issue 1 , January 2024, , Pages 323-343


  Tunnel Boring Machines (TBMs) are extensively used to excavate underground spaces in civil and tunneling projects. An accurate evaluation of their penetration rate is the key factor for the TBM performance prediction. In this study, artificial intelligence methods are used to predict the TBM penetration ...  Read More

Airflow inside tunnel boring machine: A numerical study and an experimental verification

H.R. Nezarat; Seyed M. E. Jalali; M. Nazari

Volume 10, Issue 3 , July 2019, , Pages 623-632


  Knowledge of the airflow distribution inside a Tunnel Boring Machine (TBM) can create a safe working environment for workers and machinery. The airflow quality and the related mass flow rate in the ventilation system should be sufficient to dilute gases and remove dust inside the tunnel. In this work, ...  Read More

A comparative study of two meta-heuristic algorithms in optimizing cost of reinforced concrete segmental lining

Seyed S. Mousavi; M. Nikkhah; Sh. Zare

Volume 10, Issue 1 , January 2019, , Pages 95-112


  In this work, we tried to automatically optimize the cost of the concrete segmental lining used as a support system in the case study of Mashhad Urban Railway Line 2 located in NE Iran. Two meta-heuristic optimization methods including particle swarm optimization (PSO) and imperialist competitive algorithm ...  Read More

Simulation of tunnel boring machine utilization: A case study

S. Moosazadeh; H. Aghababaie; Seyed H. Hoseinie; B. Ghodrati

Volume 9, Issue 1 , January 2018, , Pages 53-60


  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 ...  Read More
