Correlation of uniaxial compressive strength between UCT and point load index of rock in Klang Valley [PDF]
, 2020 Uniaxial compressive strength (UCS) is one of the most important properties of rock that are widely used in geotechnical field. Since, the direct method to obtain UCS is expensive; Point Load Test (PLT) is the most commonly used method to estimate UCS ...

Strength behaviour of a model rock intersected by non-persistent joint
Journal of Rock Mechanics and Geotechnical Engineering, 2019 Several constructions in the field of civil engineering quite often need to deal with rocks. Strength behaviour of rock intersected by a discontinuity or a set of discontinuities has been a topic of keen interest for engineering community.

Deep Underground Science and Engineering, EarlyView.Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Deep Underground Science and Engineering, EarlyView.This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...
