... increment of the TP-Lisbon sand for different Sr conditions because of the strong dependency of P-wave propagation on the degree of saturation in granular media. This is a consequence of the most relevant factor conditioning the pore pressure buildup in partially saturated sands, e.g., the compressibility...

...D. Park; I. Kim; G. Kim; J. Lee The presence of groundwater level (GWL) causes changes in stiffness and strength of soil, affecting the bearing capacity and settlement of shallow foundations. In the present study, the load-carrying capacity and settlement of footings in sands under various GWL...

Guzman; Magued Iskander This study presents the geotechnical properties of a synthetic transparent soil made of fused quartz saturated with a water-based sucrose solution that is suitable for modeling the behavior of sand in small-scale model tests. Geotechnical properties presented include...

...A. J. Brennan; S. P. G. Madabhushi Saturated sands particularly at low relative density commonly exhibit rises in excess pore pressure when subjected to earthquake loading. The excess pore pressure can approach a maximum value, limited by the initial vertical effective stress. After the completion...

... conducted on sands with contrasting grain features. Results indicate that the proposed technique is capable of capturing the onset of characteristic stress-strain behavior regimes exhibited by the soil during loading. The clarity of such capture is, however, dependent on the amplitude of the AE relative...

...T Mirata; Y Erzin Limited tests had indicated peak drained values of angle of internal friction Φ of gravelly sands measured in the cylindrical wedge shear test (cylwest) to be relatively closer to the Φ expected from plane strain tests than from triaxial tests. Such a difference was not obtained...

...B Muhunthan; VS Pillai; D Olcott The energy input during shear deformation of sand is expended by three components: resistance against particle-to-particle frictional deformation, volumetric or nonrecoverable plastic deformation, and elastic deformation of the soil grains. These three components...

This constant volume test is a useful means of assessing the steady state strength of granular soils at large strain to determine the liquefaction...

...EU Klotz; MR Coop New methods of geotechnical design in sands are often based on a state parameter type of approach, requiring the in situ state of the soil to be quantified relative to its critical state line. One difficulty in the application of these methods is then the correct identification...

...ME Barton; A Cresswell; R Brown During cut and fill operations, compaction using sands from different sources may be carried out. The resulting mixed sand will have different compaction characteristics than those of the parent sands. An increase in dry density will result as the grading moves...

...A Cresswell; ME Barton; R Brown Experiments have been carried out to find the maximum dry density taken up by sands during pluviation. These experiments were facilitated by use of a flow divider that permitted very low depositional intensities. It was found that the maximum dry density occurred...
