Geotechnical investigation and testing - Geotechnical monitoring by field instrumentation - Part 3: Measurement of displacements across a line: Inclinometers (ISO 18674-3:2017)

ISO 18674-3:2017 specifies the measurement of displacements across a line by means of inclinometers carried out for geotechnical monitoring. General rules of performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills and of geotechnical works are presented in ISO 18674‑1.
ISO 18674-3:2017 also refers to deflectometers (see Annex B) to supplement inclinometers for the determination of horizontal displacements across horizontal measuring lines.
NOTE       In general, there are two independent displacement components acting across measuring lines. Inclinometers allow the determination of the two components for vertical measuring lines. For horizontal lines, inclinometers are limited to the determination of the vertical component only.
If applied in conjunction with ISO 18674‑2, ISO 18674-3:2017 allows the determination of displacements acting in any direction.
ISO 18674-3:2017 is applicable to:
-      checking geotechnical designs in connection with the Observational Design procedure;
-      monitoring of geotechnical structures prior to, during and after construction (e.g. natural slopes, slope cuts, embankments, excavation walls, foundations, dams, refuse dumps, tunnels);
-      deriving geotechnical key parameters (e.g. from results of pile load tests or trial tunnelling);
-      identification and monitoring of active shear planes in the ground.
NOTE       ISO 18674-3:2017 fulfils the requirements for the performance monitoring of the ground, of structures interacting with the ground and of geotechnical works by the means of inclinometers as part of the geotechnical investigation and testing in accordance with References [1] and [2].

Geotechnische Erkundung und Untersuchung - Geotechnische Messungen - Teil 3: Verschiebungsmessungen quer zu einer Messlinie: Inklinometer (ISO 18674-3:2017)

Dieses Dokument legt geotechnische Verschiebungsmessungen senkrecht zu einer Messlinie mit Hilfe eines Inklinometers fest. Allgemeine Regeln für die Überwachung des Verhaltens des Baugrunds, von Bauwerken, die mit dem Baugrund in Wechselwirkung stehen, von Auffüllungen und von geotechnischen Anlagen sind in ISO 18674-1 festgelegt.
Dieses Dokument bezieht sich auch auf Deflektometer (siehe Anhang B), um Inklinometer für die Bestimmung von horizontalen Verschiebungen senkrecht zu horizontalen Messlinien zu ergänzen.
ANMERKUNG   Im Allgemeinen gibt es zwei unabhängige Verschiebungskomponenten, die senkrecht zu Messlinien wirken. Inklinometer ermöglichen die Bestimmung zweier Komponenten für vertikale Messlinien. Bei horizontalen Linien sind Inklinometer lediglich auf die Bestimmung der vertikalen Komponente beschränkt.
Wenn es zusammen mit ISO 18674 2 angewendet wird, ermöglicht dieses Dokument die Bestimmung von Verschiebungen, unabhängig davon, in welche Richtung sie wirken.
Dieses Dokument gilt für:
—   die Prüfung geotechnischer Ausführungsvorschläge im Zusammenhang mit der Beobachtungsmethode;
—   die Überwachung von geotechnischen Anlagen vor, während und nach dem Bau (z. B. von natürlichen Böschungen, Böschungseinschnitten, Aufschüttungen, Baugrubenwänden, Gründungen, Dämmen, Mülldeponien, Tunneln);
—   die Ableitung geotechnischer Schlüsselparameter (z. B. von Ergebnissen von Pfahlprobebelastungen oder Probestollen);
—   Identifikation und Beobachtung von aktiven Scherebenen im Baugrund.
ANMERKUNG   Dieses Dokument erfüllt die Anforderungen an die Überwachung des Verhaltens des Baugrunds, von Bauwerken, die mit dem Baugrund in Wechselwirkung stehen, sowie von geotechnischen Anlagen mit Hilfe eines Inklinometers als Teil der geotechnischen Erkundung und Untersuchung in Übereinstimmung mit den Literaturhinweisen [1] und [2].

Reconnaissance et essais géotechniques - Surveillance géotechnique par instrumentation in situ - Partie 3: Mesurages des déplacements perpendiculairement à une ligne par inclinomètre (ISO 18674-3:2017)

Ce document spécifie la mesure des déplacements perpendiculairement à une ligne au moyen d'inclinomètres réalisés dans un but de surveillance géotechnique. Les règles générales de surveillance des performances du terrain, des structures en interaction avec le terrain, des remblais géotechniques et des travaux géotechniques sont présentées dans l'ISO 18674‑1.
Ce document fait également référence aux déflectomètres (voir l'Annexe B) en complément des inclinomètres pour la détermination des déplacements horizontaux perpendiculairement aux lignes de mesures horizontales.
NOTE       En général, deux composantes de déplacement indépendantes agissent perpendiculairement aux lignes de mesures. Dans le cas des lignes de mesures verticales, les inclinomètres permettent de déterminer ces deux composantes. Pour les lignes horizontales, les inclinomètres sont limités à la détermination de la seule composante verticale.
Si elle est appliquée conjointement à la norme ISO 18674‑2 cette norme permet de déterminer les déplacements agissant dans toutes les directions.
Ce document s'applique:
—          au contrôle des calculs géotechniques en lien avec la méthode observationnelle;
—          à la surveillance des structures géotechniques avant, pendant et après une phase de construction (p. ex. pentes naturelles, déblais, remblais, parois d'excavation, fondations, barrages, terrils, tunnels);
—          à l'obtention des principaux paramètres géotechniques (p.ex. à partir des résultats des essais de chargement de pieu ou des essais de creusement de tunnel);
—          à l'identification et à la surveillance des plans de cisaillement actifs du terrain.
NOTE       Le présent document satisfait aux exigences relatives à la surveillance des performances du terrain, des structures en interaction avec le terrain et des ouvrages géotechniques au moyen d'inclinomètres dans le cadre des études et essais géotechniques conformément aux Références [1] et [2].

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
