Geoscientific and engineering experiments in petrophysics, rock physics, and rock
mechanics depend on multiple, costly, and sometimes rare samples used to characterize the …

In the engineering of underground construction, the discontinuous structures in rock mass
have important influences on the mechanical behaviors of the subsurface of rock mass. The …

Reliable size-effect law for discontinuous rock mass is the premise of projection of the scale-
down model test results to practical engineering applications. In this study, 3D printing …

The presence of structural planes in rock masses reduces their mechanical properties and
greatly affects their failure mode, resulting in physical and mechanical anisotropy. This study …

Abstract Three-dimensional (3D) printing technology has been widely used to create
artificial rock samples in rock mechanics. While 3D printing can create complex fractures, the …

This study presents a visualized approach for tracking joint surface morphology. Three-
dimensional laser scanning (3DLS) and 3D printing (3DP) techniques are adopted to record …

Abstract 3D concrete printing has the potential to simulate physical models for engineering
investigations. However, it has not been fully exploited and validated. In this study, 3D …

The structural deterioration and associated fracture evolution behavior of pre‐flawed hollow‐
cylinder granite subjected to multi‐stage increasing‐amplitude (MSIA) cyclic loads are …

Wetting and drying cycles (WDCs) have a significant impact on the shear behavior of
discontinuities with different joint wall materials (DDJMs). This influence is crucial for the …

Flaws such as faults, joints, and bedding planes often exist in natural rock masses, which
pose significant safety hazards for tunnel excavation. We conducted a series of experimental …
