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.

Limit analysis of masonry walls using discontinuity layout optimization and homogenization
International Journal for Numerical Methods in Engineering, Volume 124, Issue 2, Page 358-381, 30 January 2023., 2023 Abstract A numerical limit analysis model for masonry walls subject to in‐plane loading is posed as a discontinuity layout optimization (DLO) problem, with the masonry conveniently modeled using a smeared continuum (“macromodeling”) approach and a homogenized yield surface.

Simulation of CO2–water two‐phase fluid displacement characteristics based on the phase field method
Deep Underground Science and Engineering, EarlyView.In the present study, a two‐dimensional numerical model of porous media was developed using the actual pore structure of the core sample. The phase field method was utilized to simulate the impact of the displacement velocity, the water–gas viscosity ratio, and the density ratio on the flow behavior of two‐phase fluids in porous media. Abstract The two‐

Near Surface Geophysics, Volume 20, Issue 6, Page 572-589, December 2022., 2022 ABSTRACT The detection of mineral deposits and their related geological structures is of great importance to the mining industry as structures (such as dykes and faults) can affect the safety, cost and efficiency of mining. With the goal of testing cost‐effective seismic methods for mineral exploration and mining, active and passive seismic experiments
