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

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

A 3D Finite-Difference Analysis of Interaction between a Newly-Driven Large Tunnel with Twin Tunnels in Urban Areas

S. Akbari; Sh. Zare; H. Chakeri; H. Mirzaei Nasir Abad

Volume 11, Issue 3 , July 2020, , Pages 809-823


  Evaluation of the interaction between a new and the existing underground structures is one of the important problems in urban tunneling. In this work, using FLAC3D, four numerical models of single- and twin-tube tunnels in urban areas are developed, where the horizontal distance between the single- and ...  Read More
