This study presents a geomechanical assessment of the stress-strain state of a rock mass near mined-out areas using numerical modeling. The aim of the research is to establish the patterns of stress redistribution and the development of inelastic deformation zones around a development working (excavation) depending on...
This paper presents a discrete fracture-matrix (DFM) model to simulate coupled fluid flow and geomechanics in fractured rock masses. Aiming at computational efficiency and accuracy, the fractures are explicitly represented by lower-dimensional zero thickness elements. The proposed numerical model is comprised of a matr...
The efficient development of unconventional reservoirs is fundamentally challenged by strong geological heterogeneity and variations in rock mechanical properties. To address this, we present an integrated workflow for high-resolution 3D geomechanical modeling to optimize hydraulic fracturing design. The methodology be...
Crest cracking represents a pervasive structural hazard during the construction and operational phases of high earth-core rockfill dams (ECRDs); consequently, the development of history-matched numerical tools is rendered an engineering necessity to prevent catastrophic risks. To address the limitations inherent in tra...
Natural fractures play a key role in controlling fluid flow and heat extraction in carbonate geothermal reservoirs. Due to the high degree of rock fragmentation and strong seismic wave absorption at the top of the carbonate formation, it is difficult to identify the distribution of natural fractures inside the carbonat...
To characterize the three-dimensional evolution of creep damage in deep roadway surrounding rock, this study establishes a COMSOL-based (Multiphysics 6.3) integrated analysis framework coupling creep damage, seismic velocity response and three-dimensional imaging. The framework adopts the Norton–Bailey creep constituti...
