Abstract
  The major factors affecting tunnel stability include the ground conditions, in-situ stresses, and project-related features. In this research work, critical strain, stress reduction factor (SRF), and capacity diagrams are used for tunnel stability analysis. For this purpose, eighteen tunnel sections are ...  Read More

The Finite Difference Analysis of Empirical Tunnel Support Design in High Stress fractured rock mass Environment at the Bunji Hydropower Project, Pakistan

Hafeezur Rehman; Wahid Ali; Kausar sultan Shah; Mohd Hazizan bin Mohd Hashim; Naseer Muhammad Khan; Muhammad Ali; Muhammad Kamran; Muhammad Junaid

Volume 13, Issue 3 , July 2022, , Pages 781-795

https://doi.org/10.22044/jme.2022.12231.2219

Abstract
  Support design is the main goal of the Q and rock mass rating (RMR) systems. An assessment of the Q and RMR system application in tunnelling involving high-stress ground conditions shows that the first system is more appropriate due to the stress reduction factor. Recently, these two systems have been ...  Read More

Evaluating Microscale Failure Response of Various Weathering Grade Sandstones Based on Micro-Scale Observation and Micro-Structural Modelling Subjected to Wet and Dry Cycles

Kausar Sultan shah; Mohd Hazizan bin Mohd Hashim; Hafeez Ur Rehman; Kamar shah bin Ariffin

Volume 13, Issue 2 , April 2022, , Pages 341-355

https://doi.org/10.22044/jme.2022.11699.2160

Abstract
  The significance of rock failure can be found from the fact that microfracture genesis and coalescence in the rock mass results in macroscale fractures. Rock may fail due to an increase in the local stress, natural fractures, weathering inducing micro-crack genesis, coalescence, and propagation. Therefore, ...  Read More

Application of Stochastic Simulation in Assessing Effect of Particle Morphology on Fracture Characteristics of Sandstone

K. Sultan shah; M. H. bin Mohd Hashim; H. Rehman; K. S. bin Ariffin

Volume 12, Issue 4 , October 2021, , Pages 969-986

https://doi.org/10.22044/jme.2021.11418.2124

Abstract
  Indirect tensile testing is used in order to investigate the effect of particle morphology (shape and size) on the various weathering grade sandstone fracture characteristics. Several fracture characteristics are discussed in depth in this work including the fracture length (FL), fracture deviation area ...  Read More

Monte Carlo Simulation-Based Uncertainty Integration into Rock Particle Shape Descriptor Distributions

K. Sultan Shah; M. H. Bin Mohd Hashim; K. Sh. Bin Ariffin

Volume 12, Issue 2 , April 2021, , Pages 299-311

https://doi.org/10.22044/jme.2021.10472.1997

Abstract
  The particles within the rock samples are present in extensive ranges of shapes and sizes, and their characterization and analysis exist with a considerable diversity. The prior research works have appraised the significance of the particle shape types and their effects on the geotechnical structures ...  Read More

A Preliminary Assessment of Rock Slope Stability in Tropical Climates: A Case Study at Lafarge Quarry, Perak, Malaysia

K.S. Shah; M. H. Mohd Hashim; K.S. Ariffin; N. F. Nordin

Volume 11, Issue 3 , July 2020, , Pages 661-673

https://doi.org/10.22044/jme.2020.9814.1901

Abstract
  The stability analysis of rock slopes is a complex task for the geotechnical engineers due to the complex nature of the rock mass in a tropical climate that often has discontinuities in several forms, and consequently, in several types of slope failures. In this work, a rock mass classification scheme ...  Read More
