Study on the Mixed Materials Proportion of Stratum Based on the Modelling Experiment

It is highly significant to select similar materials as well the proportion of mixed in model test. The are used simulate stratum test, including iron ore powder, natural sands, gypsum, and lime. contains silty clay silt soil. First all, symmetry coefficient mechanics parameters calculated by equation, ratio 16 : 1. Second, calculate compositions orthogonal deviation method analyze how influence elastic modulus, cohesion, friction angle. Finally, get which meet theory control factors.
