Road networks in low and lower-middle income countries (LIC/LMICs) are rapidly expanding to enhance social economic growth. The construction of a new road often requires cuttings be made, especially hilly topography. In LIC/LMICs, many practitioners rely on guidelines design roadside cuttings, however, some these lack accuracy as they not developed using rigorous stability analysis methods. Sta...

The direct application of the Hoek–Brown failure criterion to practical slope engineering is still an urgent problem. geometries and earthquake effect need be considered in determination linear Mohr–Coulomb (MC) strength parameters from criteria for stability analysis. This study adopted tangential method construct a three-dimensional (3D) rotational mechanism using homogeneous rock slopes unde...

In this article, an alternative numerical procedure to calculate displacements and stresses of supported circular tunnels is proposed, considering the whole process tunnel advancement, sequential installation primary secondary support systems. derivation, plastic area rock mass divided into a large number annuli around tunnel, then Finite Difference Method employed. First, strain-softening beha...

Mudstone is a widely occurring type of rock in deep mining, and it crucial to understand its failure mechanisms strength characteristics under the interaction water high stress ensure stability deeply buried engineered mudstone. In this study, composition structure mudstone were obtained, triaxial tests conducted on five different contents four confining pressures using servo press. The variati...

In this study, we present a global database of ten parameters, which include measurements rock index properties, strength stiffness and dynamic properties. Hoek-Brown constant mi, is included, was estimated, using Hoek Brown proposed guidelines for determining mi values different types that can be used preliminary design when triaxial tests are not available. This broad compiled from 96 studies...

Slates are metamorphic rocks characterized by the pervasive occurrence of cleavage or foliation producing a highly anisotropic mechanical behavior fissility. Deformability and strength these therefore dependent on plane orientations relative to principal stresses. In this study, failure deformability experimentally investigated means set standard uniaxial triaxial compression tests samples cut ...
