Geotechnical investigation and testing - Laboratory testing of soil - Part 10: Direct shear tests (ISO 17892-10:2018)

This document specifies two laboratory test methods for the determination of the effective shear strength of soils under consolidated drained conditions using either a shearbox or a ring shear device.
This document is applicable to the laboratory determination of effective shear strength parameters for soils in direct shear within the scope of geotechnical investigations.
The tests included in this document are for undisturbed, remoulded, re-compacted or reconstituted soils. The procedure describes the requirements of a determination of the shear resistance of a specimen under a single vertical (normal) stress. Generally three or more similar specimens from one soil are prepared for shearing under three or more different vertical pressures to allow the shear strength parameters to be determined in accordance with Annex B.
Special procedures for preparation and testing the specimen, such as staged loading and pre-shearing or for interface tests between soils and other materials, are not covered in the procedure of this document.
NOTE       This document fulfils the requirements of the determination of the drained shear strength of soils in direct shear for geotechnical investigation and testing in accordance with EN 1997-1 and EN 1997-2.

Geotechnische Erkundung und Untersuchung - Laborversuche an Bodenproben - Teil 10: Direkte Scherversuche (ISO 17892-10:2018)

Dieses Dokument legt zwei Laborprüfverfahren zur Bestimmung der effektiven Scherfestigkeit von Böden unter konsolidierten, drainierten Bedingungen fest, bei denen entweder ein Rahmenschergerät oder ein Ringschergerät verwendet wird.
Dieses Dokument gilt für die Laborbestimmung der effektiven Scherfestigkeitsparameter für Böden in direkten Scherversuchen innerhalb des Anwendungsbereiches geotechnischer Untersuchungen.
Die in dieses Dokument aufgenommenen Versuche gelten für ungestörte, gestörte, wiederverdichtete oder aufgearbeitete Böden. Das Verfahren beschreibt die Anforderungen zur Bestimmung des Scherwiderstands eines Probekörpers unter einer einzigen vertikalen (Normal-)Spannung. Im Allgemeinen werden drei oder mehr ähnliche Probekörper aus einem Boden für das Abscheren unter drei oder mehr verschiedenen vertikalen Spannungen hergestellt, um die Scherfestigkeitsparameter in Übereinstimmung mit Anhang B bestimmen zu können.
Spezielle Verfahren für die Herstellung und Prüfung von Probekörpern, z. B. stufenweise Belastung und Vorscheren (Anscheren), oder für Grenzflächenuntersuchungen zwischen Böden und anderen Materialien sind nicht Teil des Verfahrens in diesem Dokument.
ANMERKUNG   Das vorliegende Dokument erfüllt die Anforderungen an die Bestimmung der drainierten Scherfestigkeit von Böden bei direktem Scheren für die geotechnische Erkundung und Untersuchung nach EN 1997 1 und EN 1997 2.

Reconnaissance et essais géotechniques - Essais de laboratoire des sols - Partie 10: Essai de cisaillement direct (ISO 17892-10:2018)

Le présent document spécifie deux méthodes de détermination de la résistance au cisaillement effective des sols dans des conditions consolidées drainées par essais de laboratoire en utilisant soit une boîte de cisaillement, soit un dispositif de cisaillement annulaire.
Ce document s'applique à la détermination en laboratoire des paramètres de résistance au cisaillement effective des sols en conditions de cisaillement direct dans le cadre d'investigations géotechniques.
Les essais présentés dans ce document s'appliquent aux sols non remaniés, remoulés, recompactés ou reconstitués. La procédure décrit les exigences applicables à la détermination de la résistance au cisaillement d'une éprouvette soumise à une contrainte verticale (normale) unique. En général, au moins trois éprouvettes similaires d'un même sol sont préparées en vue de les soumettre au cisaillement sous au moins trois pressions verticales différentes afin de pouvoir déterminer les paramètres de résistance au cisaillement conformément à l'Annexe B.
Les procédures spéciales de préparation et d'essai des éprouvettes, telles que le chargement par étapes et le pré-cisaillement, ou destinées aux essais d'interface entre les sols et les autres matériaux, ne sont pas couvertes par la procédure du présent document.
NOTE       Le présent document répond aux exigences applicables à la détermination de la résistance au cisaillement drainé des sols soumis à un cisaillement direct pour la reconnaissance et les essais géotechniques conformément aux normes EN 1997‑1 et EN 1997‑2.

Geotehnično preiskovanje in preskušanje - Laboratorijsko preskušanje zemljin - 10. del: Neposredni strižni preskus (ISO 17892-10:2018)

Ta dokument določa dve laboratorijski preskusni metodi za določevanje efektivne strižne trdnosti zemljin v konsolidiranih dreniranih pogojih s strižnikom ali pripomočkom za krožno striženje. Ta dokument se uporablja za laboratorijsko določevanje parametrov efektivne strižne trdnosti za zemljine v neposrednem strigu, ki spada na področje uporabe geotehničnega preiskovanja.
Preskusi iz tega dokumenta so namenjeni za neporušene, ponovno pregnetene, ponovno zgoščene ali obdelane zemljine. V postopku so opisane zahteve za določevanje strižne odpornosti primerka pri enkratni navpični (normalni) obremenitvi. Običajno so pripravljeni trije ali več primerkov za striženje pod tremi ali več različnimi navpičnimi pritiski, da se lahko določijo parametri strižne trdnosti v skladu z dodatkom B.
Posebni postopki za pripravo in preskušanje primerka, kot sta stopenjska obremenitev in predstriženje,
oziroma za vmesne preskuse med zemljinami in drugim materialom v postopku iz tega dokumenta niso obravnavani.
OPOMBA: Ta dokument izpolnjuje zahteve za določevanje drenirane strižne trdnosti zemljin v neposrednem strigu za geotehnično preiskovanje in preskušanje v skladu s standardoma EN 1997-1 in EN 1997-2.
