Abstract

Abstract Based on dynamic triaxial experimental results for basalt fibre-reinforced coral aggregate concrete (BFRCAC), the dynamic Mohr–Coulomb (M − C), Hoek–Brown (H–B), and Drucker–Prager (D–P) strength criteria for BFRCAC are established. The results show that the dynamic strength of BFRCAC increases with an increase in the strain rate and confining pressure. The cohesion c of BFRCAC calculated using the M − C strength criterion increases, while the internal friction angle θ decreases with an increase in the strain rate. The parameter m of the H–B strength criterion decreases with the increase in the strain rate. The variations in the cohesive force cDP and internal friction angle θDP of BFRCAC, as calculated using the D–P strength criterion, are consistent with the variations in c and θ. Through a comparison of the least mean standard deviation mismatch, the dynamic H–B strength criterion shows a higher calculation accuracy.
