Study on physico‑mechanical characterization of rock-like material with bedding planes under coupled static and dynamic cyclic loadings

Underground rocks are often subjected to seismic waves and blasting excavation, which cause significant changes in physical and mechanical properties. Due to the bedding plane, the mechanical properties of layered rocks with different dip angles become particularly complex under dynamic disturbance. To investigate the damage mechanism of layered specimens under coupled dynamic and static loading, dynamic disturbance tests were conducted on rock-like material with bedding planes. The results show that the cycle times (C) negatively correlate with the peak load. The linearity of the fit is high, with R2 values above 97
