WebGTX's fully equipped laboratories perform more than 100 different soils tests to determine physical properties. We provide these services in support of all types of earthwork applications. Our automated equipment permits us to run any type of consolidation, triaxial, or direct shear test a client specifies. WebMar 5, 2024 · Triaxial testing is a method used to determine the stress-strain properties of soils by subjecting soil samples to constant lateral pressure while increasing vertical pressure. This test measures stresses in three mutually perpendicular directions.
WebDec 4, 2012 · The CU test includes pore pressure measurements during the shearing phase. Therefore, the effective stresses can be calculated. The UU test is a glorified unconfined compressive strength test. The CU test can model a proposed long term loading condition. The UU provided an estimate of short term shear strength at the existing condition. WebFeb 11, 2024 · 5.3 The shear strength determined from this test method can be expressed in terms of effective stress because a strain rate or load application rate slow enough to allow pore pressure dissipation during shear is used to result in negligible excess pore pressure conditions. The shear strength may be applied to field conditions where full drainage can …
