Evolution of Pore Structure and Fractal Characteristics in Red Sandstone under Cyclic Impact Loading

Fractal and Fractional, Journal Year: 2024, Volume and Issue: 8(8), P. 437 - 437

Published: July 24, 2024

Fatigue damage can occur in surface rock engineering due to various factors, including earthquakes, blasting, and impacts. The underlying cause for the variations physical mechanical properties of resulting from impact loading is alteration internal pore structure. To investigate evolution characteristics structure under fatigue damage, red sandstone subjected cyclic compression by split Hopkinson pressure bar (SHPB) was analyzed using nuclear magnetic resonance (NMR) technology. parameters describing were obtained quantified fractal methods. development rocks quantitatively analyzed, two models based on size connectivity constructed. results indicate that with an increasing number cycles, porosity gradually increases, T2 cutoff (T2c) value decreases, most probable gray imaging (MRI) pores’ enhanced, dimension decreases gradually. Moreover, distribution space tends transition three-dimensional two-dimensional, suggesting expansion dominant pores into clusters, forming microfractures or even macroscopic fissures. findings provide valuable insights a microscopic perspective contribute evaluation time-varying stability assessment progressive engineering.
