| 摘 要： | 水田表层土壤由于含水量较高,其承压特性与其他土壤有较大区别。经观测高含水量土壤在平板测头作用下的流动规律,并测定其压力—沉陷关系表明:Bekker的压力—沉陷公式不适用于高含水量土壤。通过分析,导出了高含水量土壤的压力—沉陷公式。试验结果表明,预测值与实测值相当一致。该文还分析了土壤粘度、压板面积、贯入速度对平板贯入阻力的影响。

| Abstract: | 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. |
