| Research Abstract |
To clarify the soil compaction phenomena by heavy agricultural vehicle passes on Isahaya reclamation land, soil compaction test by a tractor with a rotary tiller, soil tests such as the compaction test, oedometer test, triaxial compression test etc., and soil compaction simulations using the finite element analysis program based on the unconventional elastoplastic constitutive model and their evaluations have been investigated in this bstudy.
