WitrynaIn this case, the lateral strain of the soil mass is neglected. The testing procedure to quantify the critical soil properties associated with soil consolidation is the Oedometer Test. The term “Oedometer” derives from the Ancient Greek language and means “to swell”. The test is one of the most commonly conducted, and important ... Triaxial tests are used along with other tests to make such engineering predictions. During the shearing, a granular material will typically have a net gain or loss of volume. If it had originally been in a dense state, then it typically gains volume, a characteristic known as Reynolds' dilatancy . Zobacz więcej A triaxial shear test is a common method to measure the mechanical properties of many deformable solids, especially soil (e.g., sand, clay) and rock, and other granular materials or powders. There are several … Zobacz więcej There are several variations of the triaxial test: Consolidated drained (CD) In a 'consolidated drained' test the sample is consolidated and sheared in compression slowly to allow pore pressures built … Zobacz więcej • Civil engineering • Direct shear test • Earthworks (engineering) • Effective stress • Geotechnical engineering Zobacz więcej For soil samples, the specimen is contained in a cylindrical latex sleeve with a flat, circular metal plate or platen closing off the top and bottom ends.
