Undrained compressive strength
Web摘要： In this study, two cases of excavation to failure were utilized to investigate reasonable analysis methods for basal heave analysis. Three types of tests were carried out to obtain the undrained shear strength of clay in excavations, including the field vane (FV) shear test, the triaxial unconsolidated undrained (UU) shear test, the Ko-consolidated … Web5.8.4.2 Evaluation and use of test results. (1) The test result is the approximate value of the unconfined compressive strength of the tested soil. (2) The undrained shear strength cu …

Web9.3.1 Introduction As the name implies, the undrained shear strength s u refers to a shear condition where water does not enter or leave the cohesive soil during the shearing process. In essence, the water content of the soil must remain constant during the shearing process.

Web25 May 2015 · The lack of convergence of the intact and reconstituted samples at high stresses may be a reflection of the strength of the clay aggregates in the natural clay, which are more easily broken down by the reconstitution process than by one-dimensional compression to high stresses.
WebThe undrained triaxial strength tests are used to determine the shear strength of a soil sample that is not allowed to drain. The test will be completed on three unsaturated soil samples. The test results will be analyzed to determine the Mohr-Coulomb failure envelope, failure angle, shearing resistance, and Young’s Modulus of Elasticity. hoover high school dsmWebThe unconsolidated, undrained compressive strength of the soil is the maximum deviator stress obtained during the test under the selected confining pressure.
