| Abstract: |
| :Physical model test is an important technical means of research on the stability of rock and soil engineering ,the selection of materials in the model test and the optimal mixing proportion is the key to a successful test.In this paper ,taking a Underground-mining bauxite as the background,combined with the conditions of mining technology,based on the similarity theory,determine similar geometric constants of the model test as Cl=100,similar constants of density as Cρ=1.7.Through the rock mechanics test indoor,select material of river sand and gypsum as simulation of rock mass,combined with the fuzzy comprehensive evaluation method,materials with different sand gypsum ratio was preferred analysis,consequently determine the material with ratio of sand and gypsum 8:1 to simulate the Underground-mining bauxite. |
