摘要：
Preparing similar materials of uranium-bearing granite surrounding rocks in high-level radioactive waste geological disposal repository is the prerequisite for the similar simulation test of the radon exhalation mechanism. The samples of uranium-bearing granite were prepared based on the model similarity principle. The optimized proportion of the samples was obtained by testing their density, compressive strength, elastic modulus, and tensile strength and conducting polar sensitivity analysis and quadratic multiple regression analysis. The radon diffusion coefficient and other properties between the sample and the original rock were verified by similarity ratio, and it meets the requirements.
