EFFECTIVE STRESS RANDOM FINITE ELEMENT ANALYSIS OF CEMENT-TREATED CLAY GROUND
This study dealt with the random behavior of cement-admixed soil. In this thesis, an advanced constitutive model for cement-admixed soil was firstly incorporated in finite element program. Then the numerical model was recalibrated and validated using cell test results. Parametric studies were …

Implementation and evaluation of a recently developed rate-dependent effective stress soil model 'MIT-SR'
… The results show that that disturbances of the stress field play a vital role in the interpretation undrained shear strength. For the FDPM case, using the same expansion rate, the disturbed NC RBBC can have as low as 40% of the undrained shear strength of the undisturbed NC RBBC. In contrast, …

Modeling the relation between suction, effective stress and shear strength in partially saturated granular media
… characteristics) of soils are related to soil's "effective stress", i.e. the stress carried by the solid matrix. The remaining stress is carried by the pore fluid in the form of pore pressure. In unsaturated soils, the coexistence of water and air results in negative pore pressure, which are …

Laboratory Self-Weight Consolidation Testing of Dredged Material Analyzed Using a One-Dimensional Finite Strain Consolidation Method
… a complete relationship between void ratio and effective stress for all expected void ratios in a dredged layer, which can be determined from laboratory testing. The United States Army Corps of Engineers (USACE) suggests using a self-weight consolidation test apparatus to obtain void …

Cyclic deformation of a clay
… deformation. The effects of strain amplitude and stress history on the peak shear stresses, the mean effective stress and the specific damping energy were investigated. Mean effective stress, which showed negligible cyclic variation, decreased progressively during dynamic loading except that for …
