Evolution of Seepage Flow Rate in a Single Rough Fracture at Different Fractal Dimensions
Geofluids, Volume 2025, Issue 1, 2025.The hydraulic characteristics of a single rough fracture are critical in rock seepage studies, with roughness being the dominant factor influencing fracture hydraulic behavior. In this study, four sets of single rough fractures with fractal dimensions ranging from 1.2 to 1.8 were generated using the Weierstrass–Mandelbrot function, and the evolution of
