Influence of Load Duration and Load Ratio on Preconsolidation Pressure

open access: yesJournal of Engineering and Sustainable Development, 2008
Preconsolidation pressure is a very important parameter, which describes the stress history and affects the behavior of the cohesive soil in geotechnical engineering.

Preconsolidation pressure from piezocone tests in marine clays [PDF]

open access: yesGéotechnique, 1987
Piezocone penetration tests were carried out at five sites in marine clay with overconsolidation ratios ranging from 1·3 to 4·8 A simple model for the behaviour of these clays indicates that the effective vertical yield stress mobilized along the cone axis during penetration is equal to the difference between the actual induced total vertical stress ...

Structural changes in latosols of the cerrado region: II - soil compressive behavior and modeling of additional compaction

open access: yesRevista Brasileira de Ciência do Solo, 2011
Currently in Brazil, as in other parts of the world, the concern is great with the increase of degraded agricultural soil, which is mostly related to the occurrence of soil compaction.

Spatial patterns of preconsolidation pressure and soil moisture along transects in two directions under coffee

open access: yesRevista Brasileira de Ciência do Solo, 2011
Information on the spatial structure of soil physical and structural properties is needed to evaluate the soil quality. The purpose of this study was to investigate the spatial behavior of preconsolidation pressure and soil moisture in six transects ...

MODELING OF SOIL LOAD-BEARING CAPACITY AS A FUNCTION OF SOIL MECHANICAL RESISTANCE TO PENETRATION

open access: yesRevista Brasileira de Ciência do Solo, 2015
Estimation of soil load-bearing capacity from mathematical models that relate preconsolidation pressure (σp) to mechanical resistance to penetration (PR) and gravimetric soil water content (U) is important for defining strategies to prevent compaction of

On the evaluation of pre-consolidation pressure of undisturbed saturated clays

open access: yesHBRC Journal, 2017
The objective of this research was to show the effect of sample disturbance on the values of pre-consolidation pressure бc by using Schmertmann method. A prediction of бc form pocket penetrometer is also achieved.

Loading rate effect on mechanical properties of an unsaturated silty sand [PDF]

open access: yesMATEC Web of Conferences, 2021
This paper presents the results of an experimental study on the effects of testing rate on stress-strain behavior and volumetric changes of soil. A series of suction-controlled triaxial tests has been performed on reconstituted specimens of a silty sand (

Effect of strain rate on consolidation behavior of Ariake clay and selection of the suitable strain rate

open access: yesYantu gongcheng xuebao, 2017
The effect of strain rate on the consolidation behavior of Ariake clay is investigated by the constant rate of strain (CRS) consolidation tests under different strain rates, and the suitable stain rate in CRS consolidation tests is discussed based on the

Pressão de preconsolidação e intervalo hídrico ótimo como indicadores de alterações estruturais de um latossolo e de um cambissolo sob cana-de-açúcar Preconsolidation pressure and least limiting water range as indicators of structural changes of a latosol and a cambisol under sugarcane

open access: yesRevista Brasileira de Ciência do Solo, 2008
A identificação dos impactos da colheita mecanizada da cultura da cana-de-açúcar sobre a estrutura do solo em diferentes classes pode-se tornar uma importante estratégia de manejo para a minimização dos efeitos da compactação.

Physical properties of a Brazilian sandy loam soil after the traffic of a military vehicle M113 BR [PDF]

open access: yesRevista Brasileira de Ciência do Solo, 2020
Soil physical properties can be changed after vehicle traffic, especially by heavy military tracked vehicles. The Santa Maria military Instruction Field, where the experiment was carried out, is currently the most used area for armored tracked vehicles ...
