Disclosed a method, a system, a device, and a medium for determining load-bearing deformation of solid waste materials. The method includes: obtaining a bulk sample of solid waste material, sieving the sample to obtain multiple particle sizes, and measuring the mass of each particle size before the experiment; performing a compaction experiment on the bulk sample to obtain a stress-strain relationship curve, and calculating a slope of a linear part; sieving the bulk sample after the compaction experiment to obtain multiple particle sizes, and measuring a mass of each particle size; plotting a mass ratio diagram before and after the experiment, and calculating a relative breakage rate Band a measured fractal dimension; constructing a macroscopic strain relationship equation, substituting the measured fractal dimension into the equation to obtain a macroscopic strain, and thereby determining load-bearing deformation degree of the solid waste materials.
