Geotechnical investigation and testing - Laboratory testing of soil - Part 5: Incremental loading oedometer test (ISO 17892-5:2017)

ISO 17892-5:2017 specifies methods for the determination of the compressibility characteristics of soils by incremental loading in an oedometer.
ISO 17892-5:2017 is applicable to the laboratory determination of the compression and deformation characteristics of soil within the scope of geotechnical investigations.
The oedometer test is carried out on a cylindrical test specimen that is confined laterally by a rigid ring. The specimen is subjected to discrete increments of vertical axial loading or unloading and is allowed to drain axially from the top and bottom surfaces. Tests may be carried out on undisturbed, remoulded, recompacted or reconstituted specimens.
The stress paths and drainage conditions in foundations are generally three dimensional and differences can occur in the calculated values of both the magnitude and the rate of settlement.
The small size of the specimen generally does not adequately represent the fabric features present in natural soils.
Analysis of consolidation tests is generally based on the assumption that the soil is saturated. In case of unsaturated soils, some of the derived parameters may not be appropriate
NOTE          This document fulfils the requirements of the determination of the compressibility characteristics of soils in the oedometer for geotechnical investigation and testing in accordance with EN 1997?1 and EN 1997?2.

Reconnaissance et essais géotechniques - Essais de laboratoire sur les sols - Partie 5: Essai de chargement par palier à l'oedomètre (ISO 17892-5:2017)

La présente Norme internationale spécifie des méthodes de détermination des caractéristiques de compressibilité des sols par essai à l'œdomètre sur sol saturé.
La présente Norme internationale est applicable à la détermination en laboratoire des caractéristiques de compression et de déformation du sol dans le domaine d'application de la reconnaissance géotechnique.
L'essai à l'œdomètre est réalisé sur une éprouvette d'essai cylindrique confinée latéralement par un anneau rigide. L'éprouvette est soumise à un chargement ou déchargement vertical et axial par paliers, tout en étant drainée axialement par le haut et par le bas. Les essais peuvent être réalisés sur des éprouvettes de sol non remanié ou remanié.
Les chemins de contraintes et les conditions de drainage sous des fondations sont généralement tridimensionnels, et des différences peuvent apparaître au niveau des valeurs calculées pour le tassement ou pour sa vitesse.
La petite dimension de l'éprouvette ne permet généralement pas de représenter correctement les hétérogénéités présentes dans les sols naturels.
L'analyse d'un essai de consolidation repose généralement sur l'hypothèse que le sol est saturé. Dans le cas de sols non saturés, certains paramètres déduits de l'essai peuvent ne pas être corrects.
NOTE       Le présent document satisfait aux exigences de détermination des caractéristiques de compressibilité des sols par essai à l'œdomètre pour la reconnaissance et les essais géotechniques conformément à l'EN 1997‑1 et à l'EN 1997‑2.

Geotehnično preiskovanje in preskušanje - Laboratorijsko preskušanje zemljin - 5. del: Edometrski preskus s postopnim obremenjevanjem (ISO 17892-5:2017)

Ta dokument je namenjen določanju lastnosti stiskanja, nabrekanja in konsolidacije zemljin. Cilindrični preskusni vzorec je bočno zaprt, podvržen diskretnim intervalom z navpičnim osnim obremenjevanjem ali razbremenjevanjem, pri čemer je dovoljena drenaža vzdolž osi z zgornje in s spodnje površine.
Glavni parametri, ki so pridobljeni z edometrskim preskusom, se nanašajo na stisljivost in stopnjo primarne konsolidacije zemljin. Včasih je mogoče pridobiti tudi ocene predkonsolidacijskega tlaka, stopnje sekundarnega stiskanja in značilnosti nabrekanja.
