Abstract: Through fatigue load and coupling tests, as well as scanning electron microscope (SEM) and mercury intrusion pressure (MIP) analyses, the mechanical properties and microstructure evolution of basalt fiber reinforced concrete (BFRC)were investigated under the influence of coupling effects. The mechanism of basalt fiber (BF) inhibition of mechanical property attenuation was revealed, and the influence coefficients of BF on flexural strength and relative dynamic modulus were proposed. Results indicate that the mechanical properties of concrete under coupling conditions exhibit a “rising-declining” trend. The BF influence coefficients show that the improvement effect of BF on the decay of mechanical properties is most significant at the late stage of coupling. At the end of the coupling process, BFRC’s flexural strength, along with the relative dynamic modulus, decreased by 29.04% and 41.7%, respectively, compared to the reference concrete. During 0 to 60 000 cycles, compaction due to wheel load supplementation initially filled pores, followed by the generation of new pores, accelerating the “coarsening” of the concrete pore structure. The percentage of multi-hazardous pores increased linearly, while the percentage of harmless pores decreased linearly. The increase in BFRC porosity decreased by 35.91% compared to the baseline concrete. The decay of BFRC’s mechanical properties was significantly influenced by porosity and harmless pores. The relative dynamic modulus of BFRC decreased by 29.04% and 41.7% compared to the baseline concrete. The pore structure deterioration process involves three stages:compaction, expansion, and penetration. BF retards the formation of main cracks in the interfacial transition zone by bridging cracks and increasing crack complexity, thus mitigating the attenuation of BFRC’s mechanical properties.
