<p>Laboratory tests are often used to understand dynamic soil behavior and to develop cyclic soil constitutive models. However, the loading paths in lab tests are different from those in the field, resulting in the inaccurate prediction of site response. An ...

<p>Many empirical and theoretical CPT interpretation methods are broadly accepted and used in practice. These approaches tend to consider whether the cone penetration is drained or undrained, and then will consider the soil as either &ldquo;sand&rdquo; or ...

<p>When an earthquake occurs, the surrounding soil and the structural elements can exhibit non-linear behaviour. In common practice, only non-linear behaviour of structural elements is evaluated. But, actually, the soil reaches the limit of its elastic behaviour ...
Reference: RIVISTA ITALIANA DI GEOTECNICA 2/2008
<p>Based on conceptual frameworks of soil behavior and published experimental data related to stress and strain thresholds, alternative cyclic strain regime divisions and the cyclic strain thresholds that represent the change in soil behavior are proposed. ...

This paper presents a synthesis of mechanisms related to structure development of surficial heavy clay soils. These clay soils develop specific structural features due to wet/dry cycles and desiccation cracking they undergo during soil "ripening". There is ...

The theory of Zero Extension Lines (ZEL), based on the solution of soil plasticity equations along ZEL directions, has wide applications in determination of the bearing capacity and load–displacement behavior of foundations and retaining walls. It is known ...

<p>This paper presents a survey of seven unique case-history sites, along with a review of the techniques used in analyses of downhole seismic records. These techniques include correlation and spectral analyses, stress-strain imaging, and system identification ...

<p>During liquefaction, a shear-induced dilatancy mechanism may be one of the major factors that dictate soil behavior. As shear strain accumulates, this dilative tendency results in instants of excess pore pressure drop, sharp acceleration spikes, and associated ...

A simple elastoplastic strainhardening model of soil and soft rock behaviour is presented. The physical meaning of the few constitutive parameters characterizing the constitutive law is discussed and the procedure for their determination is outlined. Typical ...

Virtually every soil "lives" in that all of its properties undergo changes with time - some insignificant, but others very important. Time-dependent chemical, geomicrobiological, and mechanical processes may result in compositional and structural changes that ...
