Geotechnical investigation and testing - Field testing - Part 4: Prebored pressuremeter test by Ménard procedure (ISO 22476-4:2021)

This document specifies equipment requirements, the execution of and reporting on the Ménard pressuremeter test.
This document describes the procedure for conducting a Ménard pressuremeter test in natural grounds, treated or untreated fills, either on land or off-shore.
The pressuremeter tests results of this document are suited to a quantitative determination of ground strength and deformation parameters. They can yield lithological information in conjunction with measuring while drilling performed when creating the borehole (according to ISO 22476-15). They can also be combined with direct investigation (e.g. sampling according to ISO 22475-1) or compared with other in situ tests (see EN 1997-2).

Geotechnische Erkundung und Untersuchung - Felduntersuchungen - Teil 4: Pressiometerversuch nach Ménard (ISO 22476-4:2021)

Dieses Dokument legt Anforderungen an die Ausrüstung, die Durchführung und die Berichte in Zusammenhang mit dem Pressiometerversuch nach Ménard fest.
Dieses Dokument beschreibt das Verfahren zur Durchführung eines Pressiometerversuchs nach Ménard in natürlichen Baugründen, behandelten oder unbehandelten Aufschüttungen, zur Anwendung entweder an Land oder vor der Küste.
Die Ergebnisse der Pressiometerversuche nach diesem Dokument sind für eine quantitative Bestimmung der Festigkeits- und Verformungsparameter von Boden geeignet. In Verbindung mit der Messung während des Bohrens eines Bohrloches können sie lithologische Angaben liefern (nach ISO 22476 15). Sie können auch mit der direkten Erkundung (z. B. Probenahme nach ISO 22475 1) kombiniert oder mit weiteren In situ-Versuchen verglichen werden (siehe EN 1997 2).

Reconnaissance et essais géotechniques - Essais en place - Partie 4: Essai pressiomètrique dans un forage préalable selon la procédure Ménard (ISO 22476-4:2021)

Le présent document spécifie des exigences relatives à l’appareillage, à l’exécution et aux rapports pour un essai pressiométrique Ménard.
Le présent document décrit le mode opératoire pour conduire un essai au pressiomètre Ménard dans des terrains naturels, dans des couches traitées ou non traitées, sur terre ou en milieu maritime.
Les résultats des essais pressiométriques du présent document permettent une détermination quantitative de la résistance du terrain et des paramètres de déformation. Ils peuvent fournir des informations lithologiques en conjonction avec les mesures effectuées au cours du forage (selon l'ISO 22476-15). Ils peuvent aussi être combinés avec des investigations directes (par exemple des essais conformes à l’ISO 22475-1) ou comparés à d’autres essais in situ (voir l’EN 1997-2).
