Rock Mechanics
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

Evaluation the Effect of Blast Pattern on Overbreak Area around the Miyaneh-Ardabil Railway Tunnel

Sajjad Khalili; Masoud Monjezi; Hasel Amini Khoshalan; Amir Saghat foroush

Volume 15, Issue 3 , May 2024, , Pages 1149-1160


  Determining the appropriate blasting pattern is important to prevent any damage to the tunnel perimeter in conventional tunneling by blasting operation in hard rocks. In this research work, the LS-DYNA software and numerical finite element method (FEM) are used for simulation of the blasting process ...  Read More

Finite Element Analysis of Seismic Hazard in Post-mining Environments of Closed Underground Hard Rock Mines

Praveena Das Jennifer; Porchelvan P

Volume 15, Issue 1 , January 2024, , Pages 73-96


  This paper presents a comprehensive study on the stability of the deep underground closed Kolar Gold Fields mine (3.2 km deep) under varying seismic loading conditions. The study utilized the Finite Element Method (FEM)-based Midas GTS NX software tool to conduct numerical simulations of seismic loads ...  Read More

A Study on Seismic Analysis of Underground Tunnels for Delhi Metro

Rahul Shakya; Manendra Singh

Volume 14, Issue 3 , July 2023, , Pages 731-754


  Due to fast urbanization, there is a shortage of above-ground surfaces. Thus to reduce this shortage of above-ground surface, underground tunnels are constructed beneath the structure for transportation purposes. As a result, it is critical to understand how earthquakes affect underground tunnels, so ...  Read More

Compressive Failure Analyses of Rock-Like Materials by Experimental and Numerical Methods

M. Davood Yavari; H. Haeri; V. Sarfarazi; M. Fatehi Marji; H. A. Lazemi

Volume 12, Issue 3 , July 2021, , Pages 769-783


  Investigating the crack propagation mechanism is of paramount importance in analyzing the failure process of most materials. This process may be exposed during each kind of loading on the materials. In this work, the cracking mechanism in rock-like materials is studied using the numerical methods and ...  Read More

A numerical analysis of effect of segmental lining joints on tunnel support internal forces under seismic loading

I. Kheyrandish; M. Ahmadi; H. Jahankhah

Volume 10, Issue 4 , October 2019, , Pages 979-999


  During an earthquake, the better performance of segmental tunnel lining, compared to the continuous in-cast concrete lining, is generally related to the joints between segments. In order to better understand the influence of the segment joints, their effect on the internal forces induced in tunnel lining ...  Read More

Numerical analysis of slide-head-toppling failure

H. Sarfaraz; M. H. Khosravi; M. Amini

Volume 10, Issue 4 , October 2019, , Pages 1001-1011


  In layered and blocky rock slopes, toppling failure is a common mode of instability that may occur in mining engineering. If this type of slope failure occurs as a consequence of another type of failure, it is referred to as the secondary toppling failure. “Slide-head-toppling” is a type ...  Read More

A finite element model to simulate magnetic field distribution and laboratory studies in wet low-intensity magnetic separator

P. Karimi; A. Khodadadi Darban; Z. Mansourpour

Volume 10, Issue 3 , July 2019, , Pages 717-727


  Low-intensity magnetic separators are widely used in the research works and the industry. Advancement in the magnetic separation techniques has led to an expansion in the application of this method in different fields such as enrichment of magnetic mineral, wastewater treatment, and medicine transfer ...  Read More

Rock Mechanics
Stability analysis of support systems using a coupled FEM-DFN model (Case study: a diversion tunnel at Lorestan dam site, Iran)

M. Noroozi; R. Rafiee; M. Najafi

Volume 9, Issue 2 , April 2018, , Pages 485-497


  Various structural discontinuities, which form a discrete fracture network, play a significant role in the failure conditions and stability of the rock masses around underground excavations. Several continuum numerical methods have been used to study the stability of underground excavations in jointed ...  Read More
