In the selection and design of foundation system, it is important to determine the types and properties of the soil. In a detailed investigation, the conventional approach is to perform subsurface investigation to obtain for a sufficient number of soil samples which are then tested in the laboratory to obtain the necessary soil properties, including consolidation parameters. The basic index properties are water content, dry density, void ratio, consistency limits. Consolidation tests are expensive and time consuming. In order to obtain realistic values, special sampling and testing techniques...
