Some applications of Cam-clay in numerical analysis
… was conducted to model undrained and drained triaxial compression tests to investigate the relative importance of the critical state soil parameters and streis history on the calculated soil behaviour. The values of these parameters covered the range of most commonly occurring natural soils. …

Għadira sands as compared to normally consolidated deposits at Marsa (Ta’ Ċeppuna) : using static triaxial tests
… are being presented. A series of nine undrained triaxial compression tests were performed on these soils, at three different confining pressures, ranging from 55 to 1200kPa for clean sands, and 200 to 800kPa for the alluvial deposits. The behaviour of clean sands was observed to follow the …

Chemomechanics of calcium leaching of cement-based materials at different scales : the role of CH-dissolution and C-S-H degradation on strength and durability performance of materials and structures
… cement pastes and mortars is evaluated through triaxial compression tests and uniaxial tension tests, revealing an important strength loss and an increased pressure sensitivity of the materials at failure, associated with leaching. A micromechanical approach for the homogenization of the elastic …

The influence of effective consolidation stress on the normalized extension strength properties of resedimented Boston blue clay
… variation of undrained shear parameters during triaxial compression. Undrained triaxial compression tests on RBBC (Resedimented Boston Blue Clay) have shown that the soil stiffness and strength is dependant on the vertical consolidation effective stress and that the strength behaviour does not …

Normalized mechanical properties of resedimented Gulf of Mexico clay from Integrated Ocean Drilling Program Expedition Leg 308
… using recovered Leg 308 sediment. A seven triaxial compression tests, Ko consolidated, were performed to ascertain these mechanical properties as a function of consolidation stress. Consolidation stress for these specimen ranges from 150 kPa up to 1,200 kPa. Axial strain induced on the soil …

Shear and consolidation behavior of slurry-deposited, desiccated tailings and compacted filtered tailings
… sheared undrained. Consolidated undrained (CU) triaxial compression tests were conducted on 64-mm-diameter specimens that followed two different procedures. Slurry-deposited tailings were desiccated to a target void ratio and water content, resaturated, and tested in isotropic, consolidated, …

Scale effects in tests on footings
… and of absolute and relative particle size, in tests on vertically loaded footings. Two granular materials, namely, a silica rock flour and a Chatelet flint grit, which differed in nominal diameter by a factor of 50 but were otherwise practically similar in all other grain characteristics were …

Engineering properties of Resedimented Ugnu Clay from the Alaskan North Slope
… Thirteen constant rate of strain (CRS) tests were performed to ascertain the compression properties as a function of consolidation stress. Consolidation stress for these specimens ranged from 6,800 kPa to 39,000 kPa. CRS results show that the compression ratio (CR) decreases with …

An experimental study on time-dependent behaviour of reconstituted clayey soils in 1D and triaxial compression
… experimental program consists of oedometer and triaxial compression tests on compacted lightly overconsolidated natural soils (high plastic Regina clay and low plastic Calgary till) as well as on artificial soil mixtures made by mixing pure kaolinite or bentonite with crushed Opal, silt or …

Characterization of a reconstituted low plasticity silt
… and Isotropic and Ko-consolidated undrained triaxial compression (CIUC and CKoUC) tests to define the engineering properties of the material. The experimental investigation finds that undercompaction is the best reconstitution technique for this material and it is almost impossible to test …

The consolidation and strength behavior of mechanically compressed fine-grained sediments
… overconsolidation ratio (OCR). Ko-consolidated triaxial compression tests were performed on eight resedimented soils at room temperature. The results demonstrate conclusively that the conventional assumption of these soils exhibiting constant normalized properties is not valid when behavior is …

Influences of Test Conditions and Mixture Proportions on Property Values of Soil Treated with Cement to Represent the Wet Method of Deep Mixing
… curing. Unconfined compressive strength (UCS) tests and unconsolidated-undrained (UU) triaxial compression tests were conducted. Secant modulus of elasticity were determined from bottom platen displacements, deformations between bottom platen and cross bar, and from LVDT's placed directly on …

Experimental study of shear behaviour of high density polyethylene reinforced sand under triaxial compression
… capacity. In consideration of this, a series of triaxial tests were undertaken to investigate the reinforcing effect of High-Density Polyethylene (HDPE) plastic material in Cape Flats sand, predominant in the Western Cape region of South Africa. Plastic strips of various lengths were randomly …

Effects of nonhomogeneous cementation in soils on resistance to earthquake effects
… commencing the test program, a number of index tests were performed on the uncemented and cemented sand used during the laboratory investigation. It was revealed that cementation leads to increased void ratios which distort relative density calculations used to compare cemented and uncemented …
