The effect of soil and grout mixture on the ground surface settlement in mechanized excavation

Hamid Chakeri; Faezeh Barri; Mohammad Darbor; Hamed Haghkish

Articles in Press, Accepted Manuscript, Available Online from 12 April 2024


  Excavation with Tunnel Boring Machine (TBM) in urban environments can have risks, such as ground surface settlement. The empty space between the cutterhead and the segment should be filled with suitable grout during the excavation. Nowadays, using grout behind the segment and other fillers fill the empty ...  Read More

Cutting Tools Wear in Soft Ground Tunneling: Field and Experimental Insights

Sadegh Amoun; Hamid Chakeri

Volume 15, Issue 3 , May 2024, , Pages 1103-1129


  This study is an attempt to design and manufacture a tunnel boring machine (TBM) simulator to better understand the interaction between soil and cutting tools, due to the lack of an accepted method for this issue. In this paper, Sahand Soil Abrasion Test (SSAT) is introduced, which is built by the Sahand ...  Read More

Urban Tunneling Risk Management: Ground Settlement Assessment through Proportional Hazards Modeling

Ali Kazempour Osalou; Sayfoddin Moosazadeh; Ali Nouri Qarahasanlou; Mohammad-Reza Baghban Golpasand

Volume 15, Issue 3 , May 2024, , Pages 1161-1175


  Nowadays, tunnel excavation plays a major role in the development of countries. Due to the complex and challenging ground conditions, a comprehensive study and analysis must be done before, during, and after the excavation of tunnels. Hence, the importance of study and evaluation of ground settlement ...  Read More

Soil Arching and Ground Deformation around Tunnels in Sandy Grounds: Review and New Insights

Ghorban Khandouzi; Mohammad Hossein Khosravi

Volume 15, Issue 2 , April 2024, , Pages 731-759


  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

Investigating Effect of Soil Grading Parameters on Tool Wear in Mechanized Tunneling using EPB-TBM Machine

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

Volume 15, Issue 1 , January 2024, , Pages 301-321


  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

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
