Abstract: Based on decoupled technique and superposition principle, an applied mathematical modelling method was developed to analyze soil-roadway-vehicle interaction and roadway sinkage for a rapidly deployable foldable roadway. A tensionless soil-structure model was applied to model the interaction between the soil and the roadway. The roadway is flexible longitudinally and rigid transversely. The three-dimensional (3D) plate-like problem was decoupled by two two-dimensional (2D) structural models, a longitudinal membrane-like structural model and a transverse elastic beam model. The total sinkage of the roadway is the superposition of the calculations of these two structural models. The mathematical modelling is consistent with the experimental result and its rationality has been verified.
