Selecting and designing the most suitable support systems are crucial for securing
underground openings, limiting their deformation and ensuring their long-term stability …

As an innovative and efficient rock breaking method, free face-assisted rock breaking is
usually applied to tunnel excavation with TBM multi-stage cutterhead. To reveal the free face …

The closure behavior of fractured rock, which is a crucial characteristic, is challenging to
simulate accurately using commonly employed numerical models. To address this issue and …

In this study, quadratic element formulations (ie, ten-node tetrahedral elements and twelve-
node cohesive elements) are proposed to improve the computational accuracy of the three …

This paper proposes a novel mesoscale modelling method to study the effect of steel fibres
on the fracture properties of steel fibre reinforced concrete (SFRC) based on an integrated …

The combined finite-discrete element method (FDEM) is a powerful numerical tool to
simulate the transition of materials from continuous deformation to discontinuous fracturing …

In this paper, a 2D distinct element method (DEM) model of a deep tunnel in an
underground coal mine is built to thoroughly evaluate the effects of yielding (D-bolt and …

In the past, the number of CPU cores/threads was usually less than 8/16; now, the maximum
number is 128/256. As a CPU-based parallel method, OpenMP has an increasing …

Numerical methods are very important in geotechnical and geological engineering. This
study presents a reduced-order numerical model to approximate the displacement and …

The assessment of yielding rockbolt performance during rockbursts with actual seismic
loading is essential for rockburst supporting designs. In this paper, two types of yielding …
