Web2 Specific Gravity Test Introduction. The specific gravity (G s)of a material is the ratio of the mass of a unit volume of soil solids at a specific temperature to the mass of an equal volume of gas-free distilled water at the same temperature.The specific gravity of soil is usually reported at 20°C. Practical Application. The specific gravity of soil solid is used in … WebSoil piping is a naturally occurring, hydraulic process that leads to the development of macropores (large, air-filled voids) in the subsurface that are associated with landslides …

WebMar 22, 2024 · Soil-Structure Interaction. In civil engineering practice, two methods for modelling structure-soil interaction are commonly used. The beam/plate sitting on an elastic foundation is one way, while the continuum method, which employs finite element analysis (FEA), is another. These approaches take into account the soil and structure deformation.
