Roadbed rolling process modeling method for simulating field rolling effect

The invention relates to the technical field of construction simulation, in particular to a roadbed rolling process modeling method for simulating a field rolling effect, which comprises the following steps: determining a grading curve of a soil-rock mixture numerical simulation sample; establishing a soil-rock mixture numerical simulation sample, and simulating particles with different particle sizes; selecting a particle contact model and endowing particle material parameters; establishing a correlation between the two-dimensional porosity and the actual compaction degree in numerical simulation; determining the equivalent load of the reduced-scale runner wheel; generating a wall body and generating a fixed number of particles according to the height of the filler; applying self-weight stress to consolidate the filler; arranging a measuring circle to monitor the effects of different depths; and simulating the rolling process to obtain a simulation result of the rolling process.
