A novel construction approach for the pore structure model principally focuses on the controllable roundness of rock particles

Deep Underground Science and Engineering, EarlyView.
Particle rounding effects comparison of different methods: (a), (b), and (c) are the rounding results using the B‐spline curve method with different R; (d), (e), and (f) are the results of vertex rounding substitution method with different rounding radii.

Numerical investigation of the correlations of hydraulic and elastic characteristics in diverse carbonate rock types

Deep Underground Science and Engineering, EarlyView.
We use the linear Boolean model and the discrete Fourier transformation approach to generate various carbonate rocks. The lattice Boltzmann method and the finite element method are applied to calculate permeability and elastic wave velocity, respectively.

Investigation of the failure characteristics of fissure tunnels under dynamic and static combinations

Deep Underground Science and Engineering, EarlyView.
This article aims to investigate the dynamic fracture response of fractured tunnel models under zero geological stress through physical experiments and numerical simulations. It further simulates the dynamic fracture characteristics of fractured tunnel models under geological stress ranging from 0 to 2.5 MPa using the numerical software AUTODYN ...

Data‐driven analysis of the spatial dependence of grouting efficiency during tunnel excavation

Deep Underground Science and Engineering, EarlyView.
Prediction of grouting efficiency using machine learning is enhanced by adopting a training strategy that accounts for the grouting process across multiple rounds. Abstract Grouting with water–cement mixtures is the most widely used and cost‐effective method for managing excess water inflow during tunnel construction.
