Soil consolidation refers to the process by which the volume of a partially or fully saturated soil decreases due to an applied stress. When a load is applied to a low permeability soil, it is initially carried by the water that exists in the porous saturated soil and result in a rapid increase of pore water pressure.

WitrynaHoltz and Gibbs (1956) developed a simple test called free swell test for the determination of swell potential of a soil. The test is performed by pouring 10cm. 3. of soil passing 425µm sieve into a graduated cylinder glass jar of 100ml capacity filled with wa-ter. The swollen volume of the soil is observed after 24 hours. WitrynaThere is also a close relationship between the limits and properties of a soil such as compressibility, permeability, and strength. This is thought to be very useful because as the determination of Atterberg limits is relatively simple, it is more difficult to determine compressibility, permeability, and strength.

WitrynaThe oedometer test apparatus that was used to determine swelling pres- sure is shown in Figure 1. Swell potential under any surcharge is taken as the ratio of the increase … WitrynaThe test is one of the most commonly conducted, and important, laboratory tests in geotechnical engineering. The Oedometer Test aims at measuring the vertical displacement of a cylindrical, saturated soil sample subjected to a vertical load while it is radially constrained.

WitrynaDuring swelling phase soil loses strength, increases volume, exerts high swelling pressure and behaves like soft material. For these reasons, constructions on expansive soil are considered to be unsafe.
