Abstract
A soil parameter required when civil engineering/mechanical simulations for various grounds are performed is appropriately determined. A parameter determination device determines a parameter of a particle model used in a ground analysis system. The parameter determination device includes a triaxial compression test numerical analysis unit configured to determine the parameter so that the adhesive force and the shear resistance angle of a virtual ground respectively match the adhesive force and the shear resistance angle of an actual ground with a predetermined accuracy, and a pull-out test numerical analysis unit configured to determine the parameter so that a ground reaction force coefficient of the virtual ground matches a ground reaction force coefficient of the actual ground with a predetermined accuracy.
