Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. In t...

Phenomenological equations (with coeecients to be determined by speciied experiments) for the poroelastic behavior of a dual porosity medium are formulated and the coeecients in these linear equations are identiied. The generalization from the single porosity case increases the number of independent coeecients for volume deformation from three to six for an isotropic applied stress. The physica...

This study investigated the behavior of spudcan foundation jack-up vessels offshore wind turbines during undrained vertical penetration into thin stiff-over-normally consolidated clay. Large deformation finite element (LDFE) analyses were used to simulate continuous seabed surface. Detailed parametric analysis was performed explore a range normalized soil properties and layer geometry roughness...

The use of column-like elements for improving both the settlement performance and bearing capacity foundations constructed over soft soils is well understood large groups columns supporting an infinitely wide load, such as embankments slabs. However, little still lightly loaded, low-rise structures supported by pad on a finite number stone columns, particularly when crust layer present at top s...

Atterberg limits are important index parameters used to classify soils for various engineering applications. Engineering properties of predicted through simple correlations with and thereby the behavior qualitatively assessed. There two popular methods determining liquid limit, plastic limit is commonly determined adopting rolling thread methods. To avoid operator related variations in by conve...

This paper describes triaxial compression tests conducted to determine the effect of fiber inclusion on stiffness and deformation characteristics of sand-gravel mixtures. Tested soil was a mixture of Babolsar sand from the shores of the Caspian Sea and Karaj River gravel. Portland cement was used as the cementing agent and fibers 12mm in length and 0.023mm in diameter at 0%, 0.5% and 1.0% were ...

The coupled mechanics of fluid-filled granular media controls the physics of many Earth systems such as saturated soils, fault gouge, and landslide shear zones. It is well established that when the pore fluid pressure rises, the shear resistance of fluid-filled granular systems decreases, and as a result catastrophic events such as soil liquefaction, earthquakes, and accelerating landslides may...
