<p>Soil liquefaction is conventionally evaluated through an empirical framework based on accumulated experience from case histories - the "NCEER Method". However, the empirical framework contains inconsistent physics and characterizations that are unrelated ...

<p>It has been known that soil shear strength parameters are stress level dependent. On the other hand, foundation size has a significant effect on the level of imposed stress on subsoil elements. In this study, the Zero Extension Lines (ZEL) method, which ...

The kinematic approach of limit analysis is explored in three-dimensional
3D stability analysis of slopes. A formal derivation is first shown indicating that, in a general case, the approach yields an upper bound to the critical height of the slope or an ...

<p>A numerical procedure for the preliminary estimation of the earthquake-induced settlement of concrete face rockfill dams is presented. The method is based on a simple constitutive model that accounts for the key features of the behavior of coarse grained ...

In this paper a plasticity constitutive model for sands is proposed, which combines a bounding surface framework for large cyclic strains with a Ramberg-Osgood-type hysteretic formulation for relatively smaller strains.

An approximate calculation, based on bearing capacity theory, is presented for the ultimate capacity of an unreinforced or reinforced unpaved road, idealized as a granular fill over clay. The calculation is calibrated against rigorous numerical analyses to ...

Limit loads on footings (bearing capacity) can be conveniently analyzed using the kinematic approach of limit analysis. Nonsymmetrical loads on strip footings include the horizontal component of the load and the moment. They can be also represented as load ...

<p>Recent records of seismic site response have documented a salient liquefaction-induced cyclic shear-deformation mechanism. During liquefaction, these ground acceleration records have suggested a possible strong influence of soil-skeleton dilation at large ...

Limit loads on finite layers of weak soil over a rigid base are analyzed using the upper bound approach. The soil is considered cohesive, and the Tresca yield condition is used to describe its strength. Strength increasing with depth is considered, and different ...

Critical state models are highly successful in reproducing the behavior of soft clays as far as the major differences between elastic and plastic behavior are concerned. However, they are not able to model the non-linear behavior of soils at small strains. ...
