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

A new rockbolt test system was developed to investigate the dynamic response of
prestressed rockbolts. The test system involved the modification of a split Hopkinson …

This paper modified the original structural elements of pile in FLAC3D to analyse the
performance of rock bolts. For the contact surface between the bar and the binding grout …

Bolt-grouting support is an effective means for addressing the difficulty of fractured
surrounding rock control in underground engineering. In this paper, to determine the …

Numerical simulation is a useful tool in investigating the loading performance of rock bolts.
The cable structural elements (cableSELs) in FLAC3D are commonly adopted to simulate …

Ground anchors are responsible for maintaining the stability and integrity as well as
controlling the deformation, displacement, and crack development in the surrounding …

Rockbolt performance may vary differently under complex geological and stress conditions,
especially dynamic disturbance at deep underground mining. Therefore, reinforcement …

A numerical model of fully grouted bolts is proposed in this study by implementing the tri-
linear bond–slip relationship of bolts into the numerical framework presented by Hyett et …

An analytical model for the behaviour of fully grouted cable bolts under axial loading
condition is provided in this paper. This theoretical approach considers the elastic, softening …

In this paper, the potential of the five latest artificial intelligence (AI) predictive techniques,
namely multiple linear regression (MLR), multi-layer perceptron neural network (MLPNN) …
