Model Computation of Subsoil Stress Distribution and Compaction Due to Field Traffic

摘要

To evaluate the effect of field traffic on the density of the subsoil under different conditions of loading and compactibility (depending on soil type and moisture conditions) the numerical model SOCOMO has been developed. SOCOMO calculates stress distributions under wheels. Calculations of the principal stress distribution caused by a wheel loading agree well with measurements in the field. By means of techniques originally developed for air-photography two-dimensional density distributions from traffic experiments on a sandy soil have been photographed and digitized. The calculated and measured depth of the area where plastic deformations occur is almost the same and reaches till 80 cm.
