to measure the shear strength properties of a soil. It is noted that the shear strength of a material is a term used to describe a materials ability to resist failing in the direction parallel to the applied force‚ and therefore an important soil property to be noted by engineers. In this lab test ‘Sydney Sand’ is used to determine the relationship between a given load and a change in cross-sectional area and also show the friction angle of the soil specimen‚ by testing the sample using what is commonly

Irene Ubay Professor Submitted on: October 8‚ 2012 I. Introduction Vane shear test is used to measure the shear strength of a soil. It also estimated and measured the fully saturated clay’s undrained shear strength without derangement in the specimen. This test can

Consolidated Undrained Triaxial Testing of a Fine Grained Soil Introduction A consolidated undrained triaxial test was carried out by 16 separate groups to give a broad appreciation of soil behaviour by plotting the resulting effective stress paths. Results To determine the value of Skempton’s B‚ the cell pressure was increased by 100kpa. The value of B indicates whether the sample is saturated or not; a value approaching 1 is expected for a fully saturated material. The change in pore water

Introduction The unconsolidated undrained (UU) Triaxial Test is a quick method of estimating the shear strength of a soil. The soil which undergoes the test is sheared to failure without prior consolidation meaning this test is perfect for soil samples which are undisturbed however this is never the case. This means that results have to be interpreted with care so the undrained shear strength of the soil is not underestimated. For the purpose of this test I used the results posted by Dr.Brian Mc Cabe on blackboard

Advantages and disadvantages of the test Advantages: I. The control of drainage conditions to allow for different types of test: drained and undrained conditions. II. The possibility of the measurement of pore pressure III. The possibility to allow the soil to be sheared to failure in its natural weakest plane. IV. The shear strength parameters obtained is more accurate than those obtained from shear box test. Disadvantages: I. Influence of the value of intermediate principal stress. In many practical

the process of getting a converged stresses for the start of the analysis). This initial stress specification has a great impact on the subsequent steps. i.e. Deviation of the initial stress values from the actual‚ would result in incorrect higher soil displacements of the model which in turn leads to instabilities and analysis termination. • ABAQUS calculates the stresses (total stress) which is in equilibrium with the external loading (in this case it is gravity) and boundary conditions.
