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

https://doi.org/10.22044/jme.2023.13676.2532

Abstract
  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

Abstract
  The instability of the roof and walls of the tunnels excavated in coal mines has always attracted the attention of the miners and experts in this field. In this work, the instability of the main tunnels of the mechanized Parvadeh coal mine in Tabas, Iran, at the intersection with coal seam is studied. ...  Read More

Semi-Analytical Study of Settlement of Two Interfering Foundations Placed on a Slope

H. Haghgouei; A. Reza Kargar; M. H. Khosravi; M. Amini

Volume 12, Issue 2 , April 2021, , Pages 457-470

https://doi.org/10.22044/jme.2021.10509.2001

Abstract
  In many engineering constructions, the foundations should be built adjacent to each other. Therefore, the effect of interfering of close foundations should be considered in the design stage. In this research work, the effect of interference of closely separated foundations resting on a slope on the elastic ...  Read More

Numerical Stability Analysis of Undercut Slopes Evaluated by Response Surface Methodology

H. Sarfaraz; M. H. Khosravi; T. Pipatpongsa

Volume 12, Issue 1 , January 2021, , Pages 31-43

https://doi.org/10.22044/jme.2020.10199.1957

Abstract
  One of the most important tasks in designing the undercut slopes is to determine the maximum stable undercut span to which various parameters such as the shear strength of the soil and the geometrical properties of the slope are related. Based on the arching phenomenon, by undercutting a slope, the weight ...  Read More

Physical modelling of caving propagation process and damage profile ahead of the cave-back

V. Heydarnoori; M. H. Khosravi; M. Bahaaddini

Volume 11, Issue 4 , October 2020, , Pages 1047-1058

https://doi.org/10.22044/jme.2020.9845.1908

Abstract
  The cavability assessment of rock mass cavability and indicating the damage profile ahead of a cave-back is of great importance in the evaluation of a caving mine operation, which can influence all aspects of the mine operation. Due to the lack of access to the caved zones, our current knowledge about ...  Read More

Development of a New Experimental Technique for Dynamic Fracture Toughness Measurement of Rocks using Drop Weight Test

Gh. Khandouzi; H. Memarian; M. H. Khosravi

Volume 11, Issue 3 , July 2020, , Pages 909-920

https://doi.org/10.22044/jme.2020.9818.1903

Abstract
  The dynamic fracture characteristics of rock specimens play an important role in analyzing the fracture issues such as blasting, hydraulic fracturing, and design of supports. Several experimental methods have been developed for determining the dynamic fracture properties of the rock samples. However, ...  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

https://doi.org/10.22044/jme.2019.8521.1731

Abstract
  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
