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.
期刊介绍：
The Journal of Terramechanics is primarily devoted to scientific articles concerned with research, design, and equipment utilization in the field of terramechanics.
The Journal of Terramechanics is the leading international journal serving the multidisciplinary global off-road vehicle and soil working machinery industries, and related user community, governmental agencies and universities.
The Journal of Terramechanics provides a forum for those involved in research, development, design, innovation, testing, application and utilization of off-road vehicles and soil working machinery, and their sub-systems and components. The Journal presents a cross-section of technical papers, reviews, comments and discussions, and serves as a medium for recording recent progress in the field.
