CEN ISO/TS 17892-10:2004

Geotechnical investigation and testing - Laboratory testing of soil - Part 10: Direct shear tests (ISO/TS 17892-10:2004)

ISO/TS 17892-10:2004 specifies laboratory test methods to establish the effective shear strength parameter for soils within the scope of the geotechnical investigations according to prEN 1997-1 and -2.
The test method consists of placing the test specimen in the direct shear device, applying a pre-determined normal stress, providing for draining (and wetting if required) of the test specimen, or both, consolidating the specimen under normal stress, unlocking the frames that hold the specimen, and displacing one frame horizontally with respect to the other at a constant rate of shear-deformation and measuring the shearing force, and horizontal displacements as the specimen is sheared. Shearing is applied slowly enough to allow excess pore pressures to dissipate by drainage so that effective stresses are equal to total stresses.
Direct shear tests are used in earthworks and foundation engineering for the determination of the effective shear strength of soils.

Geotechnische Erkundung und Untersuchung - Laborversuche an Bodenproben - Teil 10: Direkte Scherversuche (ISO/TS 17892-10:2004)

Diese Technische Spezifikation legt Laborversuchsverfahren zur Bestimmung der wirksamen Scherparameter von Böden fest im Bereich der geotechnischen Untersuchungen nach ENV 1997-1 und ENV 1997-2.
Das Versuchsverfahren besteht aus dem Einbringen des Probekörpers in das direkte Schergerät unter Aufbringung einer vorher bestimmten Normalspannung, wobei der Probekörper entwässert (und, falls erforderlich, getrocknet) wird. Es ist auch vorgesehen, den Probekörper unter Normalspannung zu verdichten, die Rahmen zum Halten des Probekörpers zu lösen und einen Rahmen horizontal gegenüber dem anderen Rahmen bei konstanter Geschwindigkeit zu verformen und die horizontale Scherkraft und Verformung zu messen. Das Scheren wird so langsam durchgeführt, dass erhöhter Porendruck über die Entwässerung abgetaut wird und somit die tatsächlichen Spannungen den Normalspannungen entsprechen.
Direkte Scherversuche werden im Erd- und Grundbau zur Bestimmung der effektiven Scherparameter von Böden durchgeführt.

Reconnaissance et essais géotechniques - Essais de laboratoire sur les sols - Partie 10: Essais de cisaillement direct (ISO/TS 17892-10:2004)

L'ISO 17892-10:2004 spécifie les méthodes d'essai de laboratoire destinées à déterminer les paramètres de résistance au cisaillement effective des sols dans le domaine des reconnaissances géotechniques conformes à prEN 1997-1 et -2.
La méthode d'essai consiste à placer l'éprouvette dans l'appareil de cisaillement direct, à appliquer une contrainte normale pré-déterminée pour permettre le drainage (et l'humidification, si nécessaire) de l'éprouvette, ou à consolider l'éprouvette sous une contrainte normale, à désolidariser les boîtes horizontales qui contiennent l'éprouvette, à déplacer horizontalement une des boîtes par rapport à l'autre à vitesse de déformation constante, et à mesurer la force de cisaillement et le déplacement horizontal pendant le cisaillement de l'éprouvette. Le cisaillement est produit suffisamment lentement pour que la surpression interstitielle se dissipe par drainage de telle sorte que les contraintes effectives soient égales aux contraintes totales
Les essais de cisaillement direct sont utilisés pour déterminer la résistance effective des sols destinée au dimensionnement des ouvrages en terre et des fondations.

Geotehnično preiskovanje in preskušanje – Laboratorijsko preskušanje zemljin – 10. del: Neposredni strižni preskus (ISO/TS 17892-10:2004)

Ta dokument določa laboratorijske preskusne metode za ugotavljanje parametra efektivne strižne trdnosti za zemljine v okviru geotehničnih preiskav v skladu s prEN 1997-1 in -2. Preskusna metoda je sestavljena iz namestitve preskusnega vzorca v neposredni strižni pripomoček, vnosa vnaprej določene normalne napetosti, zagotavljanja drenaže (in po potrebi močenja) preskusnega vzorca ali obojega, utrditve vzorca pod normalno napetostjo, odklepanja okvira, ki drži vzorec, in premikanja enega okvira v vodoravni smeri glede na drugega s stalno hitrostjo strižne deformacije ter merjenja strižne sile in vodoravne premestitve ob striženju vzorca.  Striženje poteka dovolj počasi, da odvečni porni tlak izginja z drenažo in da so efektivne napetosti enake skupnim napetostim. Neposredni strižni preskusi se uporabljajo pri zemeljskih delih in temeljenju za določevanje efektivne strižne trdnosti zemljin.
