At present, the epoxy resin curing method mainly uses trial and error method to make rock-like materials, which causes great waste of resources and time. The effects of mass ratio of epoxy resin to curing agent, accelerator percentage and diluent percentage on compressive strength, elastic modulus and tensile strength of rock-like materials were studied by uniform experimental design method. The results show that the mass ratio of epoxy resin to curing agent and the percentage of accelerator and diluent have great influence on the mechanical properties of rock-like materials made by epoxy resin curing method. Rock-like materials exhibit various failure modes, primarily including vertical splitting failure, brittle tensile failure, and lateral dilatancy failure. In terms of mechanical properties, their peak compressive strength ranges from 4.79 MPa to 78.17 MPa, tensile strength ranges from 0.23 MPa to 16.74 MPa, and elastic modulus ranges from 0.23 GPa to 6.56 GPa. These mechanical properties and failure modes allow rock-like materials to simulate the characteristics of various natural rocks, including granite, basalt, and water-bearing sandstone. Based on linear regression analysis, empirical formulas are established relating the mechanical properties of rock-like materials to the mass ratio of epoxy resin to curing agent, the percentage of accelerator, and the percentage of diluent. The accuracy of these formulas is verified through experiments. The obtained formulas can provide a reference for rapidly determining the mix proportions of rock-like materials using the epoxy resin curing method.
