Method and system for updating numerical model parameters, storage medium and computer equipment

Abstract

The invention relates to the technical field of numerical simulation, in particular to a method and a system for updating numerical model parameters, a storage medium and computer equipment. The invention combines the 3D shooting technology of a three-eye stereo camera, the surface layer updating technology and the automatic point cloud processing technology to realize the geometric shape updating of the slope numerical model; combining physical model test, data mining technology of moisture content sensor and function fitting technology, the hydrological parameters of numerical model are updated; the material parameters of numerical model are updated by combining direct shear test and function fitting technology. Compared with the monitoring data of model test and the simulation results of non-updated numerical model. It can effectively solve the problems of low slope simulation accuracy and low numerical modeling efficiency. Accord to that method, the geometric position, material parameters and hydrological parameter of the slope are updated and corrected, and the numerical simulation accuracy can be improved. Simplify the process of point cloud clipping, format conversion and model import of complex slope, and improve the efficiency of establishing numerical model.
