Granular soils range in particle size from .003" to .08" (sand) and .08" to 1.0" (fine to medium gravel). Granular soils are known for their water-draining properties. Characteristics Sand and gravel obtain maximum density in either a fully dry or saturated state. Testing curves are relatively flat so density can be

Drainage conditions are supposed to have significant influence on sand liquefaction behavior. An infiltration device was utilized in cyclic triaxial tests to reproduce different drainage conditions by altering dry density of the within silt. Permeability coefficient ratio (kp) was utilized for quantifying the drainage boundary effect. Cyclic triaxial tests were conducted on saturated Fujian ...

This paper establishes a non-equilibrium thermodynamic constitutive model that can predict the undrained shear behavior of saturated sand. Starting from the basic laws of thermodynamics, the model does not require the classical concepts in elasto-plastic models, such as the yield function, the flow rule, and the hardening rule. It is also different from the existing thermodynamic constitutive ...

Appendix A. The binary packing study of McGeary (1961) and the subsequent re-analysis of his experimental data by Lade et al. (1998) provide some guidance on factors affecting the value of b.This is because b depends on the locations of fines relative to the sand skeleton, and has a subtle linkage to packing small particles within an assembly of large particles.

On the contrary, thermal effects on the stress–strain behaviour of intact specimens are negligible at zero suction. At a suction of 200 kPa, as soil temperature rises from 20 to 60 °C, the shear stiffness and maximum dilatancy of intact specimens decrease by 35% and 68%, respectively.

Compared with conventional driven piles, the behaviour of jacked piles in sand and/or sandy soil is poorly understood, mainly because of the lack of field experience and a high-quality load test database. In a few field studies on the behaviour of driven piles in sand (Lehane et al., 1993; Chow, 1995), jacking was used instead of dynamic driving
