Integrated computational-experimental soil behavior characterization from direct simple shear tests on Boston Blue Clay
… non-uniform stress-strain distribution as in the Direct Simple Shear (DSS) test. Numerous tests are often needed to fully characterize a soil’s nonlinear and anisotropic and time-dependent behavior and to develop an appropriate soil model. This study utilizes an evolutionary inverse analysis …

An investigation of liquefied shear strength using novel centrifuge tests, direct simple shear tests, and field case histories
… failures, renewed interest in the mobilized shear strength during flow liquefaction failures, usually termed the liquefied shear strength, su(liq). Statistics indicate that although the number of failures and incidents at tailings storage facilities decreased in the past 30 years or so, the …

Direct shear and direct simple shear tests: a comparative study of the strength parameters and their dependence on moisture and fines contents
Shear strength of soil is characterized by cohesion, angle of internal friction and dilatation. The first two parameters mentioned primarily define the soil's ability to resist shear stress underspecified load. These parameters can be determined by tests conducted either in the laboratory or the …

Three-Dimensional Simulations of the Behaviour of Layered Soils under Simple Shear
… the behavior of uniform and layered soils under simple shear using 3D numerical analyses, focusing on the influence of a thin clay layer within sandy soils on strength and liquefaction resistance. Comparison of 2D and 3D simulations of direct simple shear (DSS) tests highlights qualitative …

Characterization of consolidation and creep properties of Salt Lake City clays
… (reload) oedometer, 16 Ko-Consolidated phase of direct simple shear SHANSEP and six Ko-Consolidated phase of triaxial SHANSEP tests were run on radiographed tube samples to evaluate the consolidation and creep properties of the SLC clays. Comparison between the end-of-primary (EOP) compression …

Development of an Energy-based Liquefaction Evaluation Procedure
… resistance, qc1Ncs, or normalized small strain shear wave velocity, Vs1). Although rarely used in practice, the strain-based procedure is commonly cited as an attractive alternative to the stress-based framework because excess pore pressure generation (and, in turn, liquefaction triggering) is …

Hydromechanical Stress and Internal Erosion under Earthen Structures
… and testing of an Internal Erosion Plane-Stain Direct Simple Shear (PSDSS) device to evaluate internal erosion. The results indicated that within internally unstable soils internal erosion typically initiates and then may terminate or continue depending upon the hydromechanical conditions. Any …

Permanence and Life Cycle Performance of Biocementation Soil Improvement
… of different geochemical conditions. Next, direct simple shear tests were employed to examine the consequences of chemical damage on the engineering behaviors of biocemented loose sands and identify new methods by which post-treatment material damage might be detected and accounted for. …

Rapid Drawdown Analysis using the Finite Element Method
… rotation was investigated using triaxial and direct simple shear tests. Finally probabilistic methods were applied to RDD to assess the probability that the factor of safety is less than one, assuming RDD occurs.

Characterization of a reconstituted low plasticity silt
… (CRS), Hydraulic Conductivity, Ko-Consolidated Direct Simple Shear (CKoDSS), 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 …
