Thermo–Hydro–Mechanical–Chemical Coupling in Reactive Fractured Rocks With Double Porosity

The coupled thermo–hydro–mechanical–chemical equations are developed for reactive fractured rock with double porosity. The constitutive equations explicitly account for the effects of solid‐phase reactions (e.g., dissolution, precipitation) on the stress‐strain response and porosity evolution by reactions in both the f...

Experimental and Mesoscale Simulation Study on the Seepage–Stress Coupling Behavior of Cemented Sand and Gravel Materials

Cemented sand and gravel (CSG), widely used in dams and cofferdams, is susceptible to fracture under coupled seepage and mechanical loading. This study combines wedge-splitting experiments and mesoscale numerical simulations to investigate the hydro-mechanical fracture behavior of CSG under crack-face water pressures o...

Coupled Modeling of Reactive Rock-Fluid Interactions and Impurity-Tolerant CO2 Injection for Geological CCS

Geological carbon capture and storage requires both tailored CO? stream designs and robust prediction of subsurface rock-fluid behavior to ensure secure, enduring sequestration. We introduce an integrated, high-performance modeling framework that links thermodynamic evaluation of multicomponent CO2 mixtures with full...

Numerical and Experimental Study of the Effects of Water-to-Cement Ratio and Temperature on Cement-Based Materials Under Sulfate Attack

The water-to-cement ratio and temperature are key factors governing ionic transport in cement-based materials. However, quantitative descriptions of their coupled effects on sulfate ion transport–reaction processes remain limited. In this study, a coupled transport–reaction model is developed to simulate sulfate ingres...

A coupled hydro–mechanical–chemical–biological model for microbially induced calcite precipitation in soils

Microbially induced calcite precipitation (MICP) is a promising ground improvement technique involving complex coupling between hydraulic, mechanical, chemical, and biological processes. However, many existing models focus on selected processes or treat key couplings, such as precipitation-induced stress, in a phenomen...

Analysis of Hydraulic Fracture Propagation Behavior Using a Thermo-Hydro-Mechanical Coupled Model

Hydraulic fracturing is a key reservoir stimulation technology for enhancing hydrocarbon recovery from unconventional reservoirs. However, fracture initiation and propagation are governed by complex thermo-hydro-mechanical (THM) coupling processes, which strongly influence fracture geometry, propagation dynamics, and o...
