Geotechnical investigation and testing - Geotechnical monitoring by field instrumentation - Part 5: Stress change measurements by total pressure cells (TPC) (ISO 18674-5:2019)
This document specifies the measurement of stress changes by means of total pressure cells (TPC). 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.
If applied in conjunction with ISO 18674‑4, this document allows the determination of effective stress acting in the ground.
This document is applicable to:
— monitoring changes of the state of stress in the ground and in geo-engineered structures (e.g. in earth fill dams or tunnel lining);
— monitoring contact pressures at the interface between two media (e.g. earth pressure on retaining wall; contact pressure at the base of a foundation);
— checking geotechnical designs and adjustment of construction in connection with the Observational Design procedure;
— evaluating stability during or after construction.
Guidelines for the application of TPC in geotechnical engineering are presented in Annex B.
NOTE This document fulfils the requirements for the performance monitoring of the ground, of structures interacting with the ground and of geotechnical works by the means of total pressure cells as part of the geotechnical investigation and testing according to EN 1997-1[1] and EN 1997-2[2].
Geotechnische Erkundung und Untersuchung - Geotechnische Messungen - Teil 5: Spannungsänderungsmessungen mittels Druckmessdosen (ISO 18674 5:2019)
Dieses Dokument trifft Festlegungen zu Spannungsänderungsmessungen mittels Druckmessdosen. Die allgemeinen Regeln für die messtechnische Überwachung des Baugrunds, der mit dem Baugrund in Wechselwirkung stehenden Bauwerke, geotechnischer Auffüllungen und geotechnischer Bauarbeiten sind in ISO 18674 1 angegeben.
Wenn dieses Dokument in Verbindung mit ISO 18674 4 angewandt wird, erlaubt es die Bestimmung der im Baugrund wirkenden effektiven Spannung.
Dieses Dokument gilt für:
- die Überwachung von Änderungen des Spannungszustands im Baugrund und in geotechnischen Bauwerken (z. B. Erddämme oder Tunnelschalen);
- die Überwachung von Drücken an der Grenzfläche zwischen zwei Bauteilen (z. B. Erddruck auf Stützwände; Flächenlast an der Sohle einer Gründung);
- die Überprüfung geotechnischer Entwürfe und die Anpassung von Konstruktionen im Zusammenhang mit der Beobachtungsmethode;
- die Bewertung der Standsicherheit während der Ausführung und im Endzustand.
Ein Leitfaden zur Anwendung von Druckmessdosen in der Geotechnik ist in Anhang B enthalten.
ANMERKUNG Dieses Dokument erfüllt die Anforderungen an die mittels Druckmessdosen durchgeführte messtechnische Überwachung des Baugrunds, der mit dem Baugrund in Wechselwirkung stehenden Bauwerke und geotechnischer Bauarbeiten im Rahmen der geotechnischen Erkundung und Untersuchung nach EN 1997 1 [1] und EN 1997 2 [2].
Reconnaissance et essais géotechniques - Surveillance géotechnique par instrumentation in situ - Partie 5: Mesures de la variation de pression par cellules de pression totale (TPC) (ISO 18674-5:2019)
Le présent document spécifie la mesure des variations de pression à l'aide de cellules de pression totale (TPC). Les règles générales relatives à la réalisation d'un suivi du terrain, des structures en interaction avec le terrain, des remblais géotechniques et des travaux géotechniques sont présentées dans l'ISO 186741.
S'il est appliqué conjointement à la norme ISO 186744, le présent document permet de déterminer les contraintes effectives agissant dans le terrain.
Le présent document s'applique:
— à la surveillance des changements de l'état de contrainte dans le terrain et les structures géotechniques (p. ex. dans des barrages en terre ou des revêtements de tunnel);
— à la surveillance des pressions de contact à l'interface entre deux milieux (p. ex. poussée des terres sur un mur de soutènement; pression de contact à la base d'une fondation);
— au contrôle des calculs géotechniques et à l'ajustement d'une construction en lien avec la méthode observationnelle;
— à l'évaluation de la stabilité durant ou après la construction.
Les directives pour l'utilisation de TPC en génie géotechnique sont présentées à l'Annexe B.
NOTE Ce document satisfait aux exigences relatives à la surveillance du terrain, des structures interagissant avec le terrain et des travaux géotechniques au moyen de TPCs, dans le cadre de la reconnaissance et des essais géotechniques conformément à l'EN 1997-1[1] et l'EN 1997-2[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
