Acoustic emission behavior of granular soils with various ground conditions in drained triaxial compression tests

Investigation of Stress-Strain Behavior of Plastic Concrete Using Monotonic Triaxial Compression Tests

In this paper, the mechanical behavior of plastic concrete being used in the cut-off walls of earth dams has been studied. To do the task, triaxial compression tests on the specimens in various ages and mix designs under different confining pressures have been done and the stress-strain behavior of such materials and their strength parameter changes has been experimentally investigated. It has ...

Behavior of Granular Soils under Dry and Saturated Conditions in Cyclic Torsional Shear Tests

This paper presents results from drained cyclic torsional shear tests on Toyoura sand and a residual soil under dry and saturated conditions. The relationships of shear strain,   z with shear stress,   z ; normalized shear stress, z z     / ; vertical strain, z  ; and equivalent shear modulus, Geq are compared. The investigation of granular decomposition with respect to its influence o...

behavior of rockfill materials in triaxial compression testing

this paper studies thoroughly and deeply the results of about one hundred triaxial compression tests on thirty types of rockfill materials. the materials are categorized in accordance with their particles shape (angular / rounded) and gradation characteristics. the main tool of the study is the hyperbolic model developed by duncan and chang. the focus of the study is on the variations of deform...

Evaluation of undrained response from drained triaxial shear tests: DEM simulations and Experiments

مدل‌سازی رفتار خاک‌های دانه‌ای غیر‌اشباع به‌روش اجزا منفصل

Although a significant portion of conditions encountered in geotechnical engineering, for investigating engineering behavior of soil, involves unsaturated soils; the traditional analysis and design approach has been to assume the limiting conditions of soils being either completely dry or completely saturated. In unsaturated soils the capillary force produce attractive forces between particles....
