Infiltration Grouting Mechanism in Porous Media Based on Fractal Theory
To investigate the infiltration grouting mechanism of Bingham fluid in porous media, we derived formulas for calculating the apparent velocity of infiltration diffusion and the spherical infiltration grouting diffusion distance of Bingham fluid in porous media based on the fractal theory, the capillary model, and the rheological equation of Bingham fluid. We compared and validated the theoretical formulas against existing models and laboratory grouting tests. The results indicate that the diffusion radius of the grout calculated using the fractal theory-based formulas aligns more closely with experimental data compared to conventional Bingham fluid infiltration grouting formulas. These findings offer valuable theoretical support for practical grouting applications in porous media strata.
