Finite Element Analysis and Prediction of Rock Mass Permeability Based on a Two-Dimensional Plane Discrete Fracture Model

The safety of underground engineering projects is significantly influenced by groundwater. One the key complexities identifying primary seepage paths within rock formations, understanding patterns seepage, and determining effects fracture parameters on fluid movement inside mass. To address these issues, a probabilistic model constructed for random fractures using finite element method, reflecting nature distributions in real world. This allows an in-depth examination distribution pore water pressure Darcy velocity field, revealing permeability trends fractured masses. A variety models were devised to understand relationship between factors such as density, length, length power law, angle, dispersion coefficient, aperture, how they affect overall study suggests that, context discrete masses, there linear increase with density aperture. Moreover, greater lead increased permeability, aligned direction having most impact velocity. thorough investigation that each parameter was performed, computed. From findings, series predictive equations suggested estimating based geometry parameters.
