EN ISO 22476-9:2020

Geotechnical investigation and testing - Field testing - Part 9: Field vane test (FVT and FVT-F) (ISO 22476 9:2020)

This document deals with the equipment requirements, execution and reporting of field vane tests for the measurement of peak and remoulded vane shear strength together with the sensitivity of fine-grained soils. In addition, post-peak shear strength behaviour can be evaluated. Two types of field vane test are described: the ordinary field vane test (FVT) and the fast field vane test (FVT-F).
The uncertainties of the vane test result are described in Annex D.
NOTE 1  This document fulfils the requirements for field vane tests as part of the geotechnical investigation and testing according to EN 1997-1 and EN 1997-2.
NOTE 2  This document covers onshore and nearshore field vane testing.

Geotechnische Erkundung und Untersuchung - Felduntersuchungen - Teil 9: Flügelscherversuche (FVT und FVT F) (ISO 22476 9:2020)

Dieses Dokument behandelt die Anforderungen an die Ausrüstung, Durchführung und Aufzeichnung von Flügelscherversuchen für die Messung der maximalen und gestörten Flügelscherfestigkeit zusammen mit der Empfindlichkeit feinkörniger Böden. Darüber hinaus kann das Verhalten nach der maximalen Scherfestigkeit ausgewertet werden. Beschrieben werden zwei Arten von Flügelscherversuchen: der normale Flügelscherversuch (FVT, en: field vane test) und der schnelle Flügelscherversuch (FVT-F, en: fast field vane test).
Die Unsicherheiten der Versuchsergebnisse für den Flügel sind in Anhang D beschrieben.
ANMERKUNG 1   Dieses Dokument erfüllt die Anforderungen an Flügelscherversuche als Teil der geotechnischen Erkundung und Untersuchung nach EN 1997 1 und EN 1997 2.
ANMERKUNG 2   Dieses Dokument gilt für Onshore- und Nearshore-Flügelscherversuche.

Reconnaissance et essais géotechniques - Essais en place - Partie 9: Essai au scissomètre de chantier (ISO 22476 9:2020)

Le présent document traite des exigences en matière d'équipement, d'exécution et de compte-rendu des essais sur le terrain pour la mesure de la résistance au cisaillement maximale et résiduelle du sol, ainsi que de la sensibilité des sols à grains fins. En outre, le comportement de la résistance au cisaillement après le pic peut être évalué. Deux types d'essais au scissomètre de chantier sont décrits: l'essai scissométrique ordinaire (FVT) et l'essai scissométrique rapide (FVT-F).
Les incertitudes du résultat de l'essai au scissomètre de chantier sont décrites à l'Annexe D.
NOTE 1        Le présent document répond aux exigences relatives aux essais scissométriques dans le cadre de l'étude et des essais géotechniques conformément aux normes EN 1997-1 et EN 1997-2.
NOTE 2        Le présent document porte sur les essais scissométriques à terre et à proximité du littoral.
