Consolidation
This paper highlights the importance of linking regional geology to geotechnical ground investigation when estimating the pre-consolidation pressure σp of Quaternary clay deposits from piezocone tests. The work comprises a comprehensive site characterization from boring logs, piezocone tests and laboratory oedometer tests carried out at the Tubar&atild...

The scope of this paper is the back analysis of soft soil treatment case studies in which prefabricated vertical drains together with physical and vacuum surcharge were applied. Initially, the vacuum surcharge systems in vertical drains used worldwide are reviewed. The radial consolidation theory specifically developed for vacuum and physical surcharges is prese...

The aim of this paper is to draw attention to experimental evidence which may contribute to the understanding of the viscous behaviour of soft soils and, above all, present the equation for primary one-dimensional consolidation including the soil viscous resistance and the compressibility of water, with its analytical solution. Initially, a generic equation is p...

<p>Stress history is an important measurement in soils as it affects strength, stability, stiffness, and flow characteristics. The evaluation of the in-situ preconsolidation stress, or effective yield stress, from the results of piezocone penetration tests allows for an economical and expedient means to profile the stress history of clays, sands, and mixed...
