This paper introduces many types of analogue materials in China and other countries in geotechnical model tests. Combined with the study on a few geo-mechanical model tests of significant tunnels and underground openings in Chinese western areas, this paper recommends a new type of analogue material, which is made from iron mineral powder, barite powder, quartz powder and alcoholic solution with rosin. In order to know the physico-mechanical characteristics of this composite material with different mixture ratios, we use specimens to do lots of mechanical experiments such as uniaxial compressive test, quasi-triaxial shear test, triaxial test and Brazilian test. Consequently, the analogue materials with different mixture ratios can be used to physically model different projects, and this analogue material with a certain mixture ratio has been successfully used in the model test of a branching-out tunnel. The results of the model test verify that this new analogue material can be successfully used in all kinds of geotechnical model tests.
