The unloading effect of excavation is the key factor leading to rock mass instability, and bolt
support is the key means of controlling the stability. However, the original three-dimensional …

Various numerical methods have been developed for modelling rock fracturing problems.
Most of the available studies could reproduce reasonable results for given experimental …

Rocks containing various types of cracks may undergo microcrack expansion and
connection under compressive load, which leads to rock fracture under different loading …

We carried out uniaxial compression tests on brittle red sandstone with different heights. The
test results show that the uniaxial compressive strength of rock sample increases first and …

Both heterogeneity and pre-existing flaws are closely associated with the mechanical
response of crystalline granite. To uncover the underlying mechanism, grain-based model …

Cracks in rocks can lead to different load responses and mechanical properties. Primary and
secondary cracks are altered during loading, with varying degrees of impact on the failure of …

The triaxial mechanical properties of rock–concrete combined bodies are crucial for the safe
operation of concrete engineering on rock foundations. Hence, this study uses a …

Granite is a heterogeneous material characterized by a significant population of
mechanically distinct grain boundaries, which exert a substantial influence on crack …

Rapid and partial acquisition are features of rock drilling for obtaining rock properties. Most
previous research has primarily concentrated on how to quickly obtain rock mechanics …

Calibrating meso parameters is a crucial step in modeling rock materials using the Distinct
Element Method (DEM). Improved calibration methods integrating machine learning and …
