A properly designed coarser material is called a filter. 5 ft) and gradually decrease at lesser depths. Different soils with similar properties may be classified into groups and sub-groups according to their engineering behavior. Lambe (1964) proposed a technique to evaluate the elastic and consolidation settlements of foundations on clay soils by using the stress paths determined in this manner. Hence, it can be concluded that the allowable net bearing capacity for a given allowable settlement calculated using the empirical relation is safe and conservative. 112 a log sc¿ where eo in situ void ratio.
