Geotechnical investigation and testing - Testing of geotechnical structures - Part 2: Testing of piles: static tension load testing (ISO 22477-2:2023)

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 tension 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. Cyclic load tests are not covered by this document.
NOTE            ISO 22477-2 is intended to 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.
This document provides specifications for the execution of static axial pile load tests:
a)       checking that a pile behaves as designed,
b)       measuring the resistance of a pile.

Geotechnische Erkundung und Untersuchung - Prüfung von geotechnischen Bauwerken und Bauwerksteilen - Teil 2: Statisch axiale Pfahlprobebelastung auf Zug (ISO 22477‑2:2023)

Dieses Dokument enthält Festlegungen für die Durchführung von axialen statischen Pfahlprobebelastungen auf Zug an Einzelpfählen, um deren Last-Hebungsverhalten 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. Probebelastungen für zyklische Belastungen werden nicht in diesem Dokument behandelt.
ANMERKUNG   ISO 22477 2 ist in Verbindung mit EN 1997 1 anzuwenden. Zahlenwerte für die Teilsicherheitsbeiwerte für Grenzzustände und Korrelationsfaktoren, aus denen die für die Bemessung maßgebenden charakteristischen Werte aus den statischen Pfahlprobebelastungen abgeleitet werden, sind in EN 1997 1 enthalten.
Dieses Dokument enthält Festlegungen für die Ausführung statischer axialer Pfahlprobebelastungen zur
a)   Überprüfung, ob das Pfahltragverhalten mit der Bemessung übereinstimmt,
b)   Messung des Pfahlwiderstands.

Reconnaissance et essais géotechniques - Essais des structures géotechniques - Partie 2: Essai de pieux: essais de chargement statique en traction (ISO 22477-2:2023)

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 un effort de traction 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. Le présent document ne traite pas des essais de chargement cyclique des pieux.
NOTE            L’ISO 22477-2 est destinée à être utilisée conjointement avec l'EN 1997-1. Les valeurs numériques des facteurs partiels des états limites et des facteurs de corrélation servant à obtenir les valeurs caractéristiques à partir des essais de chargement statique et devant être prises en compte dans le calcul sont fournies dans la norme EN 1997-1.
Le présent document 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 - 2. del: Preskušanje pilotov: statični natezni preskus (ISO 22477-2:2023)

Ta dokument podaja specifikacije za izvedbo preskusov pilotov s statično obremenitvijo, pri čemer je pilot izpostavljen statični osni obremenitvi pod napetostjo, da se lahko določi njegovo vedenje ob premiku bremena.
Uporablja se za navpične in nagnjene pilote.
Dokument obravnava vse vrste pilotov. Preskusi v tem dokumentu so omejeni na preskuse z vzdrževano obremenitvijo. Preskusi s ciklično obremenitvijo v tem dokumentu niso zajeti.
OPOMBA: Ta dokument je treba uporabljati v povezavi s standardom EN 1997-1. V standardu EN 1997-1 so navedene 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.
Dokument podaja specifikacije za izvedbo preskusov pilotov s statično obremenitvijo, kar vključuje:
a) preverjanje, ali pilot deluje, kot je načrtovano;
b) merjenje odpornosti pilota.

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.
