Larger scale test platform for artificial rainfall induced landslide is a very important method of landslide geo-mechanical model test for studying its formation mechanism. Similar material is key issue of the larger scale test platform on all sorts of landslide research. But research on landslide model test similar material is a few. In the paper, based on geo-mechanical model tests, for to simulate apparent density, cohesion, internal friction angle, elastic modulus, Poisson's ratio and the saturated permeability coefficient of landslide, similar material parameters and its component were stated by experimental method. It is important for us to make landslide model test.
