Geotechnical investigation and testing - Geotechnical monitoring by field instrumentation - Part 1: General rules (ISO 18674-1:2015)

ISO 18674-1:2015 lays out the general rules for the performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills, and of geotechnical works.
Specifically, it applies to field instrumentation and measurements carried out: in connection with site investigations of soils and rocks, in connection with Observational Design procedures, in connection with the performance of geotechnical structures before, during, and after construction, for ground behaviour evaluation, e.g. unstable slopes, consolidation etc., for the proof or follow-up of a new equilibrium within the ground, after disturbance of its natural state by construction measures (e.g. foundation loads, excavation of soil, tunnelling), for the proof or follow-up of the stability, serviceability, and safety of structures and operations which might be influenced by geotechnical construction, for perpetuation of evidence, and for the evaluation and control of geotechnical works.

Geotechnische Erkundung und Untersuchung - Geotechnische Messungen - Teil 1: Allgemeine Regeln (ISO 18674-1:2015)

Die vorliegende Norm gilt für die Leistungsüberwachung von Baugrund, Bauwerken, die mit dem Baugrund in Wechselwirkung stehen, und geotechnische Anlagen.
Im Besonderen gilt diese Norm für die Geräteausrüstung für Feldmessungen (Feldinstrumentation) und Messungen, die durchgeführt werden
   in Verbindung mit Standorterkundungen von Böden und Fels nach EN 1997 2;
   in Verbindung mit der Beobachtungsmethode bei der Planung nach EN 1997 1;
   zur Bewertung des Verhaltens des Baugrunds, z. B. instabile Böschungen, Konsolidation usw.;
   zum Nachweis oder zur Folgeprüfung eines neuen Gleichgewichts im Baugrund nach einer Störung des natürlichen Zustands durch Baumaßnahmen (z. B. Fundamentlasten, Bodenaushub, Tunnelbau);
   zum Nachweis oder Folgeprüfung der Stabilität (Standsicherheit), Gebrauchstauglichkeit und Sicherheit von baulichen Anlagen, die möglicherweise durch geotechnische Anlagen beeinflusst werden;
   zur Beweissicherung;
   zur Bewertung und Lenkung geotechnischer Arbeiten.

Reconnaissance et essais géotechniques - Surveillance géotechnique par instrumentation in situ - Partie 1: Règles générales (ISO 18674-1:2015)

L'ISO 18674-1:2015 établit les règles générales d'exécution de la surveillance du sol, des structures interagissant avec le sol, des remblais géotechniques et des travaux géotechniques.
Elle s'applique spécifiquement à l'instrumentation déployée sur le terrain et aux mesurages réalisés : dans le cadre d'investigations in situ sur des sols et des roches; dans le cadre de la méthode observationnelle; dans le cadre de la performance des structures avant, pendant et après construction; pour l'évaluation du comportement des terrains, par exemple les pentes instables, les phénomènes de consolidation, etc.; pour la preuve ou le suivi d'un nouvel équilibre dans le terrain, après une perturbation de son état naturel par des mesures de construction (par exemple charges dues aux fondations, excavation de sol, creusement de tunnels); pour la preuve ou le suivi de la stabilité, de l'aptitude au service et de la sécurité des structures pouvant être influencées par les travaux géotechniques; pour la perpétuation des preuves; et pour l'évaluation et le contrôle des travaux géotechniques.

Geotehnično preiskovanje in preskušanje - Geotehnične meritve - 1. del: Splošna pravila (ISO 18674-1:2015)

Ta standard velja za meritve tal, struktur v povezavi s tlemi in geotehnična dela. Ta standard še zlasti velja za terenske instrumente in meritve v povezavi s preiskovanjem zemljin in kamnin v skladu s standardom EN 1997-2 v povezavi s postopkom opazovalnega projektiranja (Observational Design) v skladu s standardom EN 1997-1: za oceno vedenja tal, npr. nestabilnih pobočij, konsolidacijo itd. ali dokaz ali spremljanje novega ravnotežja tal po motnjah njihovega naravnega stanja z gradbenimi ukrepi (npr. obremenitve zaradi temeljenja, izkopa zemlje, gradnje predora); za dokaz ali spremljanje stabilnosti, uporabnosti in varnosti struktur, na katere lahko vplivajo geotehnične strukture; za ohranjanje dokazov; za ovrednotenje in nadzor geotehničnih del.

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 on
