Geotechnical investigation and testing - Laboratory testing of soil - Part 9: Consolidated triaxial compression tests on water saturated soils (ISO 17892-9:2018)
ISO 17892-9:2018 specifies a method for consolidated triaxial compression tests on water-saturated soils.
ISO 17892-9:2018 is applicable to the laboratory determination of triaxial shear strength under compression loading within the scope of geotechnical investigations.
The cylindrical specimen, which can comprise undisturbed, re-compacted, remoulded or reconstituted soil, is subjected to an isotropic or an anisotropic stress under drained conditions and thereafter is sheared under undrained or drained conditions. The test allows the determination of shear strength, stress-strain relationships and effective stress paths. All stresses and strains are denoted as positive numerical values in compression.
NOTE 1 This document provides a test for a single specimen. A set of at least three relatable tests are required to determine the shear strength parameters from these tests. Procedures for evaluating the results are included in Annex B and, where required, the shear strength parameters are to be included in the report.
Special procedures such as:
a) tests with lubricated ends;
b) multi-stage tests;
c) tests with zero lateral strain (K0) consolidation;
d) tests with local measurement of strain or local measurement of pore pressure;
e) tests without rubber membranes;
f) extension tests;
g) shearing where cell pressure varies,
are not fully covered in this procedure. However, these specific tests can refer to general procedures described in this document.
NOTE 2 This document fulfils the requirements of consolidated triaxial compression tests for geotechnical investigation and testing in accordance with EN 1997‑1 and EN 1997‑2.
Geotechnische Erkundung und Untersuchung - Laborversuche an Bodenproben - Teil 9: Konsolidierte triaxiale Kompressionsversuche an wassergesättigten Böden (ISO 17892-9:2018)
Diese Internationale Norm legt ein Verfahren für konsolidierte triaxiale Kompressionsversuche an wassergesättigten Böden fest.
Diese Internationale Norm gilt für die im Labor durchgeführte Bestimmung der triaxialen Scherfestigkeit unter Kompressionsbelastung innerhalb des Anwendungsbereichs geotechnischer Erkundungen.
Der zylindrische Probekörper, der aus ungestörtem, nachverdichtetem, aufbereitetem oder aufbereitetem und konsolidiertem Boden bestehen kann, wird einem isotropen oder anisotropen Spannungszustand unter dränierten Bedingungen ausgesetzt und anschließend unter undränierten oder dränierten Bedingungen abgeschert. Der Versuch ermöglicht die Bestimmung von Scherfestigkeit, Beziehungen zwischen Spannung und Dehnung und von wirksamen Spannungspfaden. Sämtliche Spannungen und Dehnungen sind als positive numerische Werte bei der Kompression angegeben.
Besondere Verfahren wie:
a) Versuche mit geschmierten Endflächen;
b) Mehrstufenversuche;
c) Versuche, bei denen die Querdehnungs-Konsolidation null (K0) ist;
d) Versuche mit lokaler Messung der Verformungen oder des Porenwasserdrucks;
e) Versuche ohne Gummihülle;
f) Extensionsversuche;
g) Abscheren mit veränderlichem Zellendruck;
h) Abscheren bei konstantem Volumen
werden in dieser Norm nicht vollständig behandelt. Allerdings können diese spezifischen Versuche auf allgemeine Verfahren verweisen, die in dieser Norm beschrieben sind.
ANMERKUNG Dieses Dokument erfüllt die Anforderungen an konsolidierte triaxiale Kompressionsversuche für geotechnische Erkundung und Untersuchung nach EN 1997-1 und EN 1997-2.
Reconnaissance et essais géotechniques - Essais de laboratoire sur les sols - Partie 9: Essais en compression à l'appareil triaxial consolidés sur sols saturés (ISO 17892-9:2018)
Le présent document spécifie une méthode pour les essais à l'appareil triaxial de révolution en compression sur sols saturés consolidés.
Ce document s'applique à la détermination en laboratoire de la résistance au cisaillement triaxial en conditions de chargement par compression dans le cadre d'investigations géotechniques.
L'éprouvette cylindrique, pouvant être constituée de sol non remanié, recompacté, remanié ou reconstitué, est soumise à une contrainte isotrope ou anisotrope avec un drainage et est ensuite cisaillée avec ou sans drainage. L'essai permet de déterminer la résistance au cisaillement, les relations contrainte-déformation et les chemins de contraintes effectives. Toutes les contraintes et toutes les déformations sont indiquées sous forme de valeurs numériques positives en compression.
NOTE 1: Ce document trait de la réalisation d'un essai sur une seule éprouvette. Un ensemble d'au moins trois éprouvettes est nécessaire pour déterminer les paramètres de résistance au cisaillement à partir de ces essais. Les procédures d'interprétation des résultats figurent à l'Annexe B et, le cas échéant, les paramètres de résistance au cisaillement doivent être inclus dans le rapport.
Les procédures particulières suivantes:
a) essais avec des embases lubrifiées;
b) essais en plusieurs phases;
c) essais avec consolidation à déformations latérales nulles (essais K0);
d) essais avec une mesure locale de la déformation ou de la pression interstitielle;
e) essais sans membrane en caoutchouc;
f) essais en extension;
g) cisaillement avec variations de la pression dans la cellule de l'appareil triaxial;
ne sont pas entièrement couvertes par la présente procédure. Toutefois, ces essais spécifiques peuvent faire référence aux procédures générales décrites dans le présent document.
NOTE 2 Ce document satisfait aux exigences relatives aux essais en compression à l'appareil triaxial sur sols consolidés à des fins d'investigation et d'essais géotechniques conformément aux normes EN 1997‑1 et EN 1997‑2.
Geotehnično preiskovanje in preskušanje - Laboratorijsko preskušanje zemljin - 9. del: Konsolidiran triosni tlačni preskus na z vodo zasičenih zemljinah (ISO 17892-9:2018)
Ta dokument določa metodo za konsolidirane triosne tlačne preskuse na z vodo zasičenih zemljinah. Ta dokument se uporablja za laboratorijsko določevanje triosne strižne trdnosti pod tlačno obremenitvijo, ki spada na področje uporabe geotehničnega preiskovanja.
Valjast primerek, ki je lahko sestavljen iz neporušene, ponovno zgoščene, pregnetene ali obdelane zemljine, je izpostavljen izotropni ali anizotropni napetosti pod dreniranimi pogoji in se nato striže pod nedreniranimi ali dreniranimi pogoji. Preskus omogoča določevanje strižne trdnosti, razmerij napetost–deformacija in poti učinkovite napetosti. Vse napetosti in deformacije so pri stiskanju označene kot pozitivne
številske vrednosti.
OPOMBA 1: V tem dokumentu je podan preskus za en sam primerek. Za določevanje parametrov strižne trdnosti iz preskusov je potreben nabor najmanj treh sorodnih preskusov. Postopki za vrednotenje rezultatov so vključeni v dodatek B, poročilo pa mora po potrebi vključevati parametre strižne trdnosti.
Posebni postopki, kot so:
a) preskusi z mazanimi konci;
b) večstopenjski preskusi;
c) preskusi s konsolidacijo z ničelno lateralno deformacijo (K0);
d) preskusi z lokalnim merjenjem deformacij ali lokalnim merjenjem pornega tlaka;
e) preskusi brez gumijastih membran;
f) razširitveni preskusi;
g) striženje, kjer celični tlak variira,
v tem postopku niso zajeti v celoti. Vendar ti posebni preskusi se lahko nanašajo na splošne postopke, opisane v tem dokumentu.
OPOMBA 2: Ta dokument izpolnjuje zahteve za konsolidirane triosne tlačne preskuse za geotehnično preiskovanje in preskušanje v skladu s standardoma EN 1997-1 in EN 1997-2.
