Rock mass propertiesDistinct element method3D numerical modelingIn situ stressRock supportsThe stability of the rock mass around the tunnels in an underground mine was investigated using the distinct element method. A three-dimensional model was developed based on the available geological, geotechnical, ...
In Fig. 8, the failure probability of the fractured rock mass below the red dotted line indicates stability, whereas above the line, it suggests instability. Figure 7 clearly demonstrates a negative correlation between the fractal dimension of rock mass fractures and the loading limit, indicating ...
The strength parameters for in-situ strain-softening rock mass are obtained by substituting GSI into Hoek-Brown (H-B) failure criterion. Then, E and strength parameters considering the strain-sof- tening effect are employed in the numerical procedure for solving out the rock deformation, the ...
6, when analyzing the single particle size gradations of the gangue samples under different confining pressures, it can be seen from the time-strain curves that the gangue samples with a single particle size of 20–30 mm reach the creep stability stage fastest under all four confining pressures...
Therefore, it is significant to consider the layered rock tunnel face stability subject to seismic loadings. Tu et al. (2023) and Man et al., 2022a, Man et al., 2022b evaluated the tunnel face stability in the layered rock mass. However, they did not consider the seismic effects that ...
Rockburst is a highly destructive geological hazard that can cause casualties and equipment damage. To achieve high-accuracy discrimination of rockburst in
A continuous mechanical rock properties profile is crucial to assess rock strength, analysis of wellbore stability, and sanding potentiality for reservoir management during a hydrocarbon drilling operation. Nowadays, the ML approaches are widely used to develop the data-driven predictive models for ...

(b) The view of Section A and B, pressure cells and strain gages positions around pile. Full size image In the process of landslide deformation model test, the deformation is simulated by using artificial loading or hydraulic device to apply soil thrust. The slope model takes a long time ...
Accurately determining the shear strength of structural planes is crucial for evaluating the stability of rock masses. The shear test using the sawtooth structural plane usually captures the main influencing factors of its shear characteristics. In this
