Water exerts a significant influence on the mechanical integrity of rock masses through water–rock interaction, which is directly related to the stability of deep underground engineering projects. In this study, laboratory direct shear tests and discrete element method (DEM) numerical simulations were combined to inves...
The shear mechanical properties of natural rock fracture play a vital role in resolving complex geotechnical engineering issues. Existing two-dimensional (2D) fracture models fail to capture spatial asperity distribution, while natural three-dimensional (3D) fractures are too random for systematic analysis. To address...
To investigate the shear behavior and anchoring response of bolted infilled rock joints under the combined effects of joint roughness, infill thickness, and initial mixing water content, rock-like specimens with joint roughness coefficients (JRC = 2.8–14.5), infill thicknesses (t = 0–6 mm), and initial mixing water con...
This study experimentally investigates the shear behaviours of Expanded Polystyrene (EPS) geofoam and its interfaces with structures through simple shear tests. The results demonstrate that the shear behaviours of EPS is predominantly governed by EPS density and vertical stress. Under monotonic shearing, EPS exhibits s...
