WebDec 18, 2024 · The apparatus generally used in the laboratory to determine the primary compression characteristics of a soil is known as the consolidation test apparatus (or oedometer) and is illustrated in Fig. 9.6a. The soil sample (generally 75 mm diameter and 20 mm thick) is encased in a steel cutting ring. WebIntroduction. 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.
