Partially saturated soil
WebWhen computing total vertical stress, use saturated unit weight for soil below the water table and bulk or dry unit weight for soil above water table. When the soils are partially saturated, the situation is a bit more complex. Here, the normal stress within a soil element is carried by the water, air, and the soil grains. Therefore, the Web15 May 2024 · The link between field and laboratory conditions is established by the “Soil-Water Characterization Curve” (SWCC) also called the soil retention curve. The second lecture presents the state variables by which the transition from the saturated soil condition to the unsaturated soil condition can be described, in particular the matric suction as the …
