%X It's difficult to simulate deep soft rock in rock engineering similar model experiment by using traditional similar materials due to its low strength, large deformation and strong rheology. In order to solve this problem, a mixture of 70# asphalt (due to its high output, low cost, visco-elasticity, easy molding and softening) and sea sand was adopted as similar simulation materials for deep soft rock. Uniaxial compression experiment was carried out by continuous loading, and some related parameters for similar simulation material with different ingredient ratios, such as density, compressive strength and initial elastic modulus, were analyzed, and original data and basic characteristics were obtained. The feasibility of using this similar material to simulate deep soft rock is validated and reasonable suggestions are proposed in this paper, which can be used as a reference for further model simulation experiment.
