Abstract: The reliability and accuracy of physical simulation experiment are directly influenced by the mechanical properties of model materials. In order to achieve new materials with small scale and similar as metamorphite,PRCM model material is developed and standard specimens are prepared to make further research on the mechanical parameters of the model materials. The quantitative relationships between PRCM′s proportion and uniaxial compressive strength and the effects of water on PRCM are clear. This PRCM was applied into a 3D physical simulation experiment for high-steep slope stability of Shuichang Iron Mine with satisfied results obtained.
