WebThe triaxial shear test is the most versatile of all of the methods for testing the shear strength of soil and finding its cohesion (c) and angle of internal friction (φ). It can … WebApr 13, 2024 · To demarcate internally unstable and stable soils, the microscale criterion based on the coordination number and the stress reduction factor can be used to estimate the probability of internal instability in the field at different stress state. Internal instability is a problem in railways that results in significant maintenance costs.
WebDec 13, 2024 · Under traffic loading, the soil elements in subgrade are subjected to a complex 3D stress path. To investigate the cyclic behavior of desert subgrade under initial shear stress conditions, the number of cyclic true triaxial tests were implemented on aeolian sand from the Tengger Desert. A large range of initial shear stress levels and different … WebTo identify the stress‐strain behavior of the studied low plasticity silt, several consolidated triaxial tests will be carried out under the different effective consolidation pressure and overconsolidation ratio (OCR = 1, 2, 4, 8). Under every
WebThe confined tests were conducted in a conventional triaxial cell that maintained a constant ratio between the radial and axial stress to simulate in situ loading conditions. The load ratios used were 0.25, 0.50 and 0.75. The strain rate of each test was constant at 0.01, 0.001, or 0.00001/s.
