Abstract
  Surface settlement induced by tunneling is one of the most crucial problems in urban environments. Hence, accurate prediction of soil geotechnical properties is an important prerequisite in the minimization of it. In this research work, the amount of surface settlement is predicted using three-dimensional ...  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

https://doi.org/10.22044/jme.2020.9444.1851

Abstract
  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

Numerical Modelling of Backfill Grouting Approaches in EPB Tunneling

L. Nikakhtar; Sh. Zare; H. Mirzaei Nasir Abad

Volume 11, Issue 1 , January 2020, , Pages 301-314

https://doi.org/10.22044/jme.2020.9155.1805

Abstract
  One of the main issues involved during tunnel construction with tunnel boring machines is the tail gap grouting. This gap is between the external diameter of tunnel lining and the excavation boundary that is filled with high-pressure grouting materials. In this work, three different approaches of gap ...  Read More

Development of a goal programming model for optimization of truck allocation in open pit mines

M. Mohtasham; H. Mirzaei Nasirabad; A. Mahmoodi Markid

Volume 8, Issue 3 , July 2017, , Pages 359-371

https://doi.org/10.22044/jme.2017.859

Abstract
  Truck and shovel operations comprise approximately 60% of the total operating costs in open pit mines. In order to increase productivity and reduce the cost of mining operations, it is essential to manage the equipment used with high efficiency. In this work, the chance-constrained goal programing (CCGP) ...  Read More
