Geotechnical investigation and testing - Testing of geotechnical structures - Part 1: Pile load test by static axially loaded compression (ISO/DIS 22477-1:2005)

This Standard establishes the specifications for the execution of static pile load tests in which a single pile is subjected to an axial static load in compression in order to define its load-displacement behaviour. The provisions of EN 22477-1 apply to vertical piles as well as raking piles. All types of piles are covered by this standard. The tests considered in this Standard are limited to maintained load tests.
EN 22477-1 shall be used in conjunction with EN 1997-1. Numerical values of partial factors for limit states and of correlation factors to derive characteristic values from static pile load tests to be taken into account in design are provided in EN 1997-1. Guidance on
analysis of the load testing results is given in the informative Annex D.
This Standard provides specifications for:
a) Investigation tests, whereby the pile is loaded up to failure or close to failure ;
b) Control tests, whereby the pile is loaded up to a specified load in excess of the SLS
design action.

Geotechnische Erkundung und Untersuchung - Prüfung von geotechnischen Bauwerken und Bauwerksteilen - Teil 1: Pfahlprobebelastungen durch statische axiale Druckbelastungen (ISO/DIS 22477-1:2005)

Diese Norm legt die Spezifikationen für die Durchführung statischer Pfahlprobebelastungen fest, bei denen ein einzelner Pfahl einer axialen statischen Druckbelastung ausgesetzt wird, um so sein Last Verschiebungs Verhalten zu bestimmen.
Die Bestimmungen der EN 22477 1 gelten sowohl für vertikale als auch für geneigte Pfähle.
Die vorliegende Norm deckt alle Pfahltypen ab.
Die in dieser Norm betrachteten Prüfungen sind auf lastgesteuerte Probebelastungen begrenzt.
EN 22477 1 ist im Zusammenhang mit EN 1997 1 anzuwenden. EN 1997 1 enthält Zahlenwerte der Teilsicherheitsbeiwerte für Grenzzustände und der Korrelationsfaktoren, mit deren Hilfe aus statischen Pfahlprobebelastungen Kennwerte abgeleitet werden können, die bei der Bemessung zu berücksichtigen sind. Eine Anleitung zur Analyse der Ergebnisse der Probebelastungen ist im informativen Anhang D angegeben.
Diese Norm enthält Spezifikationen für:
a)   Untersuchungsprüfungen, bei denen der Pfahl bis zum Versagen oder annähernd bis zum Versagen belastet wird;
b)   Kontrollprüfungen, bei denen der Pfahl bis zu einer festgelegten Last beansprucht wird, die über die Bemessungseinwirkung beim Grenzzustand der Gebrauchstauglichkeit hinausgeht.

ISO/DIS 22477-1
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.
ISO 22477-1 was prepared by Technical Committee ISO/TC 182, Geotechnics, Subcommittee SC 1, and by
Technical Committee CEN/TC 341, Geotechnical investigation and testing in collaboration.
ISO 22477 consists of the following parts, under the general title Geotechnical investigation and testing —
Testing of geotechnical structures:
⎯ Part 1: Pile load test by static axially loaded compression
⎯ Part 2: Pile load test by static axially loaded tens
