Geotechnical investigation and testing - Testing of geotechnical structures - Part 1: Testing of piles: static compression load testing (ISO 22477-1:2018, Corrected version 2019-03)

This document 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.
This document is applicable to vertical piles as well as raking piles.
All types of piles are covered by this document. The tests considered in this document are limited to maintained load tests. Pile load tests with constant penetration rate and cyclic load tests are not covered by this document.
NOTE       This document is intended to be used in conjunction with EN 1997-1. EN 1997-1 provides 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.
This document provides specifications for the execution of static axial pile load tests:
a)    checking that a pile will behave as designed;
b)    measuring the resistance of a pile.

Geotechnische Erkundung und Untersuchung - Prüfung von geotechnischen Bauwerken und Bauwerksteilen - Teil 1: Statische axiale Pfahlprobebelastungen auf Druck (ISO 22477-1:2018, korrigierte Fassung 2019-03)

Dieses Dokument enthält Festlegungen für die Durchführung von axialen statischen Pfahlprobebelastungen auf Druck an Einzelpfählen um deren Last Setzungs Verhalten zu bestimmen.
Dieses Dokument ist sowohl für vertikale als auch für geneigte Pfähle anwendbar.
Dieses Dokument ist für alle Pfahlarten anwendbar. Die hier enthaltenen Festlegungen gelten nur für lastgesteuerte Probebelastungen. Weggesteuerte Pfahlprobebelastungen  und zyklischen Probebelastungen werden durch dieses Dokument nicht abgedeckt.
ANMERKUNG   Dieses Dokument ist in Verbindung mit EN 1997 1 anzuwenden. EN 1997 1 enthält Zahlenwerte für die Teilsicherheitsbeiwerte für Grenzzustände und Korrelationsfaktoren, aus denen die für die Bemessung maßgebenden charakteristischen Werte aus den statischen Pfahlprobebelastungen abgeleitet werden.
Dieses Dokument enthält Festlegungen für die Ausführung statischer Pfahlprobebelastungen zur:
a)    Überprüfung, ob das Pfahltragverhalten mit der Bemessung übereinstimmt;
b)   Messung des Pfahlwiderstands.

Reconnaissance et essais géotechniques - Essais de structures géotechniques - Partie 1: Essais de pieux: essai de chargement statique en compression (ISO 22477-1:2018, Version corrigée 2019-03)

La présente norme établit les spécifications relatives à l'exécution des essais de pieux sous charge statique, au cours desquels un pieu unique est soumis à une charge de compression axiale statique afin de définir son comportement charge-déplacement.
Ce document s'applique aussi bien aux pieux verticaux qu'aux pieux inclinés.
La présente norme couvre tous les types de pieux. Les essais envisagés dans cette norme sont limités aux essais de chargement par paliers. Les essais de chargement de pieux à vitesse de pénétration constante et les essais de chargement cyclique ne sont pas couverts par la présente norme.
NOTE       Cette norme est à utiliser conjointement avec l'EN 1997‑1. La norme EN 1997‑1 fournit les valeurs numériques des facteurs partiels pour les états limites et des facteurs de corrélation servant à obtenir les valeurs caractéristiques à partir d'essais de chargement statique et devant être prises en compte dans la conception.
La présente norme fournit des spécifications pour l'exécution de l'essai de chargement axial statique de pieu pour:
a)    vérifier qu'un pieu se comporte comme prévu;
b)    mesurer la résistance d'un pieu.

Geotehnično preiskovanje in preskušanje - Preskušanje geotehničnih konstrukcij - 1. del: Preskušanje nosilnih pilotov s statično osno stiskalno obremenitvijo (ISO 22477-1:2018)

Ta standard podaja specifikacije za izvedbo preskusov pilotov s statično obremenitvijo, pri čemer je posamezen pilot izpostavljen statični osni obremenitvi pri stiskanju, da se lahko določi njegovo vedenje ob premiku bremena. Določbe iz standarda EN 22477-1 se uporabljajo za navpične in nagnjene pilote. Ta standard obravnava vse vrste pilotov. Preskusi v tem standardu so omejeni na preskuse z vzdrževano obremenitvijo. Standard EN 22477-1 je treba uporabljati v povezavi s standardom EN 1997-1. Številske vrednosti delnih faktorjev za mejna stanja in faktorjev korelacije za izpeljavo karakterističnih vrednosti iz preskusov pilotov s statično obremenitvijo, ki jih je treba upoštevati pri izdelavi, so navedene v standardu EN 1997-1. Smernice za analizo rezultatov preskusov z obremenitvijo so podane v informativnem dodatku D. Ta standard podaja specifikacije za:   a) preiskovalne preskuse, pri čemer je pilot obremenjen do okvare ali skoraj do okvare;    b) kontrolne preskuse, pri čemer je pilot obremenjen do določenega bremena, ki presega mejno stanje uporabnosti (SLS).

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
