Title:
PARAMETER DETERMINATION DEVICE, PARAMETER DETERMINATION METHOD, AND PARAMETER DETERMINATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/246247
Kind Code:
A1
Abstract:
The present invention suitably determines soil quality parameters needed for conducting civil engineering and mechanics simulations relating to various foundations. A parameter determination device 1 determines parameters for a particle model which is used by a foundation analysis system, the parameter determination device comprising: a triaxial compression test numerical value analysis unit 12 that determines a parameter so that the adhesive force and the angle of shearing resistance of a virtual foundation respectively match, with a prescribed level of accuracy, the adhesive force and the angle of shearing resistance of a real foundation; and a pull-out test numerical value analysis unit 13 that determines a parameter so that the modulus of subgrade reaction of the virtual foundation matches, with a prescribed level of accuracy, the modulus of subgrade reaction of the real foundation.
