APPLICABILITY OF SHANSEP METHOD IN EVALUATION OF PRECONSOLIDATION PRESSURE

e-GFOS, 2020
This article presents an experimental study on 81 specimens made from three different mixtures of clay and sand. To ensure uniform initial parameters, all specimens were prepared with an initial water content of 30%.

LOW-COST ELECTRO-MECHANICAL PRESS FOR DETERMINING PRE-CONSOLIDATION PRESSURE [PDF]

Engenharia Agrícola, 2022
The pre-consolidation pressure is a soil parameter indicating the maximum load that can be supported without irreversible deformation. However, the commercially available equipment for such determination is very expensive, limiting studies on this ...

Insight on bulk shear strength parameters of clay using discrete element approach incorporating physics-based interparticle force model

Soils and Foundations, 2023
This paper aims to provide insight on factors affecting the bulk shear strength parameters of clay, i.e., the cohesion and internal friction as well as the effects of memory of preconsolidation pressure.

Método alternativo de avaliação da pressão de preconsolidação por meio de um penetrômetro Alternative method for the evaluation of the preconsolidation pressure through a penetrometer

Revista Brasileira de Ciência do Solo, 2004
A curva de compressão do solo tem sido freqüentemente utilizada em estudos de compactação do solo. Essa curva representa graficamente a relação entre o logaritmo da pressão aplicada e a densidade do solo ou o índice de vazios.

Compactibility of cohesive soils from tablelands as influenced by cassava wastewater [PDF]

Ciência e Agrotecnologia, 2023
Consolidation tests give important insights into soil compactibility. However, it requires equipment that is not always available. The costal tablelands in Northeastern Brazil have extensive areas of cohesive soils where compaction is an expressive ...
