Anlysis on the Pressure-Sinkage Relationship in Paddy Field Soil With High Moisture Content

The purpose of this paper is to study the pressure-sinkage relationship under a plate in ho-mogeneous paddy soil with high moisture content, and the effects of soil viscosity, plate area and deformation rate on the pressure-sinkage relationship. According to the results of soil flow modes under the plates, using the Bingham model as the soil rheological model, the equations for pressure-sinkage relations hip are derived.The test results show that there is a good agreement between thecalculated values and the measured pressure-sinkage values.
