Determination of the compression modulus of soils from compression-test data for calculation of pile-foundation settlements

The compression moduli of clayey soils are usually assigned with very high correction factors. It is demonstrated that the basic reason for the need to correct these moduli is the requirement to account for the effect exerted by so-called leakage pressures on the skeleton of the soil specimens being tested. These leakage pressures develop due to the fact that consolidation filtration in soils is possible only when certain initial pressure gradients are attained.
