Seismic wave propagation numerical simulation method and platform, cloud equipment and computer device

The invention relates to the field of seismic oscillation numerical simulation, in particular to a seismic wave propagation numerical simulation method and platform, cloud equipment and a computer device. According to the scheme, the method comprises the steps that an SPH numerical test model is constructed, a corresponding geometric block graph is drawn based on the size of a research area, particles with the equivalent diameter being D are regularly arranged according to the interval distance D till the particles are distributed in the whole research area, the particles in the research area are real particles, the outermost layer particles of a truncation boundary are boundary particles, and the distance between the boundary particles and the truncation boundary is 0.5 D; continuously expanding at least three layers of particles to the outer side of the research area along the outer normal direction of the truncation boundary to obtain fixed virtual particles, and finally allocating physical parameters to a
