MEASUREMENT OF SOIL PROPERTIES IN DRYLAND AND WETLAND CONDITIONS

The effect of deformation rate on cone index value, plate sinkage parameters, cohesion and internal friction angle was measured in a dry, sandy loam soil and in a saturated, puddled caly soil. The effect on normal pressure on calculated values of cohesion and internal friction angle in the sandy loam soil was also investigated. Deformation rate did not greatly affect any of the soil properties in the sandy loam soil but significanly affected almost all of them in the puddled clay soil. In the sandy loam soil it is shown that normal pressure in the ring shear test must be close to that exerted by the vehicle on the soil otherwise large errors can occur in calculating cohesion and internal friction angle.
