The triaxial mechanical properties of rock–concrete combined bodies are crucial for the safe operation of concrete engineering on rock foundations. Hence, this study uses a combination of mechanical experiments, theoretical analysis, and numerical simulations to investigate the triaxial responses of different rock–concrete combined bodies under different confining pressures. The results indicate that the order of the triaxial strength and deformation resistance of rock–concrete combined bodies is G-C50, S-C50, G-C30, and S-C30, from large to...
