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. WebThe test is carried out at five stages including increasing and decreasing pressure between zero and maximum pressure. At each stage, a constant pressure is applied for an interval of 10 miniutes while pumping water. Water pressure and flow rate are measured everz minute. hungry rooster bainbridge ohio
