Geotechnical investigation and testing - Testing of geotechnical structures - Part 5: Testing of anchorages (ISO/DIS 22477-5:2005)

This European standard specifies requirements for testing of anchorages within the scope of the geotechnical investigations and testing according to ENV 1997 and to EN 1537. The purpose of this European standard is to eliminate as far as possible erroneous assessments
of anchorage conditions and mobilised forces estimated by common practice as well as to limit scatter when repeating tests and improve reproducibility when testing anchorages.

Geotechnishe Erkundung und Untersuchung - Prüfung von geotechnischen Bauwerken und Bauwerksteilen - Teil 5: Ankerprüfungen (ISO/DIS 22477-5:2005)

(1)   Diese Norm stellt Spezifikationen für die Ausführung von Zugversuchen zur Verfügung, bei denen ein Verpressanker, wie in EN 1537 definiert, schrittweise (Prüfverfahren Methode 3) oder in schrittweise gesteigerten Zyklen (Prüfverfahren Methode 1 und 2) von einer Vorbelastung bis zu einer maximalen Prüflast gespannt wird. Die Ankerkopfverschiebung wird über eine bestimmte Zeitdauer bei jeder Laststufe unter konstanter Last (Prüfverfahren Methode 3), oder bei maximaler Last in jedem Spannzyklus (Prüfverfahren Methode 1) aufgezeichnet. Der Kraftabfall am Ankerkopf wird während der Beobachtungszeit sowohl bei der Festlegekraft als auch bei der Festlegekraft eines jeden Spannzyklus gemessen (Prüfverfahren Methode 3).
(2)   Diese Norm ist anwendbar für vorgespannte Anker, bestehend aus einem Ankerkopf, einer freien Stahllänge des Zuggliedes und einer Verankerungslänge, in der Verbund mit dem Boden durch Ankermörtel hergestellt ist.
(3)   Diese Norm stellt Spezifikationen für drei Prüfungen zur Verfügung: Untersuchungsprüfung, Eignungsprüfung und Abnahmeprüfung.
(4)   Die Norm stellt Spezifikationen für die Elemente des Versuchsaufbaus, die Messeinrichtungen, die Prüfverfahren, und Vorlagen für die Darstellung der Ergebnisse sowie den Umfang der Aufzeichnungen zur Verfügung.
ANMERKUNG   Die Interpretation der Ergebnisse gehört nicht zum Anwendungsbereich dieser Norm. Hinweise werden (im informativen Anhang) gegeben für die Bestimmung des Herausziehwiderstandes Ra. eines Ankers basierend auf Untersuchungsprüfungen und für die Prüfung des Verformungsverhaltens eines Ankers auf der Basis von Eignungsprüfungen und Abnahmeprüfungen.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 22477-5 was prepared by Technical Committee ISO/TC 182, Geotechnics, Subcommittee SC 1,
Geotechnical investigation and testing.
ISO 22477 consists of the following parts, under the general title Geotechnical investigation and testing —
