Spalling is a typical brittle failure phenomenon of hard rock in deep caverns under high
geostress. In this study, key issues are systematically studied concerning the spalling failure …

In this paper, we propose a phase-field-based Lattice Boltzmann Method (LBM) model
coupled with the Discrete Element Method (DEM) for simulating unsaturated granular media …

A machine learning-based strategy is presented to estimate the contact force chains of
uniformly sized spherical granular materials under triaxial compression, using particle …

The soil–water retention curves (SWRC) of soil plays a key role in unsaturated soil
mechanics, which is a relatively new field of study having wide applications particularly in …

The main objective of this study was to investigate the primary consolidation and creep
characteristics of two unsaturated sand–bentonite mixtures subjected to drying–wetting …

Soil suction is a crucial parameter that affects the behavior of unsaturated soils. The impact
of temperature on suction can lead to significant changes in the hydromechanical response …

This paper presents a graph neural network model to estimate the contact forces of granular
materials under uniaxial compression. We show that the maximum normal contact force of …

The soil-water retention curve (SWRC) is the relationship between the suction values and
water content of the soil. This curve has one or more branches depending on the suction …

Vertical displacement (VD) estimation is one of the most important topics in construction of
an underground powerhouse cavern. This phenomenon commonly depends on excavation …

To better understand the hydro-mechanical behavior of dual porosity expansive clays, three
groups of tests were carried out. First, isotropic free drying and free wetting tests were …
