Taha Ansari; Hamid Chakeri; Mohammad Darbor; sadegh Amoun; Hadi Shakeri

Articles in Press, Accepted Manuscript, Available Online from 30 September 2023


  There is no acceptable method for investigating the tool wear phenomenon in soft grounds. In this article, first, a new equipment made at Sahand University of Technology is introduced, which is used for simulation of TBM tunneling mechanism. Next, the effect of various soil grading parameters such as ...  Read More

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

Arash Ebrahimabadi; Alireza Afradi; Mansour Hedayatzadeh

Articles in Press, Accepted Manuscript, Available Online from 01 October 2023


  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

Soil arching and ground deformation around tunnels in sandy grounds: review and new insights

Ghorban Khandouzi; Mohammad Hossein Khosravi

Articles in Press, Accepted Manuscript, Available Online from 14 November 2023


  Granular materials used in engineering structures tend to experience arching under different geotechnical factors. Arching is a factor of load transfer from the destroyed zone to stable areas in these structures. Soil arching plays an important role in stress redistribution, settlement, and load on supports ...  Read More
