The Decision of Mechanical Parameters for Numerical Simulation of Rock and Soil Mechanics

The decision of mechanical is the key step for numerical simulation of rock and soil mechanics, which determines the validity of modeling. Different mechanical parameters should be applied in different computing situations. Field scale transforming methods for deformation and strength indexes given in this paper provide good resolutions for the application of laaoratory test parameters on real situation. Finally, the methodology and steps of predictive model construction are given to gain reasonable computing model and mechanical parameters.
