The embodiment of the invention provides a simulation method and device for crack values, electronic equipment and a storage medium. The method comprises the steps that seismic wave signals, seismic focus coordinates of the seismic wave signals, propagation speed of the seismic wave signals, sampling time, time step, a geological medium density, elastic parameters of cracks, size of a grid model and length and width of each grid in the grid model are obtained; a speed-stress expression is obtained, wherein the speed-stress expression is shown in the description, and the speed values and stressvalues for simulating the seismic cracks are obtained based on the speed-stress expression, the seismic wave signals, the seismic focus coordinates, the propagation speed, the sampling time, the timestep, the medium density, the elastic parameters, the size of the grid model and the length and width of each grid in the grid model. The crack values can be simulated through the method, and the simulation precision of the values is improved.
