EN ISO 22476-12:2009

Geotechnical investigation and testing - Field testing - Part 12: Mechanical cone penetration test (CPTM) (ISO 22476-12:2009)

ISO 22476-12:2009 specifies a mechanical cone penetration test (CPTM), including equipment requirements, execution and reporting. The results from such geotechnical testing are especially suited to the qualitative and/or quantitative determination of a soil profile — together with direct investigations — or as a relative comparison with other in situ tests.
The results from a cone penetration test can in principle be used to evaluate stratification, soil type, and geotechnical parameters such as soil density, shear‑strength parameters and deformation and consolidation characteristics.
ISO 22476-12:2009 specifies the following features: type of cone penetration test; application class; penetration length or penetration depth; elevation of the ground surface or underwater ground surface at the location of the cone penetration test with reference to a datum; location of the cone penetration test relative to a reproducible fixed location reference point.

Geotechnische Erkundung und Untersuchung - Felduntersuchungen - Teil 12: Drucksondierungen mit mechanischen Messwertaufnehmern (ISO 22476-12:2009)

Dieser Teil von ISO 22476 legt Anforderungen an die Ausrüstung für mechanische Drucksondierungen sowie
deren Durchführung und Auswertung fest. Die Ergebnisse solcher geotechnischen Untersuchungen sind
insbesondere für die qualitative und/oder quantitative Bestimmung eines Bodenprofils zusammen mit direkten
Aufschlüssen oder zum relativen Vergleich mit anderen Versuchen vor Ort geeignet.
Die Ergebnisse einer Drucksondierung können prinzipiell zur Bewertung der Schichtenfolge, der Bodenart,
von geotechnischen Parametern wie Bodendichte, von Parametern der Scherfestigkeit sowie von Formänderungs-
und Konsolidationskenngrößen verwendet werden.
Dieser Teil von ISO 22476 legt folgende Merkmale fest:
- Art der Drucksondierung (siehe Tabelle 1);
- Anwendungsklasse (siehe Tabelle 2);
- Sondierlänge oder Sondiertiefe;
- Höhe der Geländeoberfläche oder des Grundwasserspiegels am Ort der Drucksondierung, bezogen auf
einen Bezugswert;
- Ort der Drucksondierung, bezogen auf einen reproduzierbaren festen Ortsbezugspunkt.
ANMERKUNG Die Planung und Beurteilung eines Untersuchungsprogramms und die Anwendung der Ergebnisse bei
der Bemessung werden in EN 1997-1 und EN 1997-2 behandelt.

Reconnaissance et essais géotechniques - Essais en place - Partie 12: Essai de pénétration statique au cône à pointe mécanique (ISO 22476-12:2009)

L'ISO 22476-12:2009 spécifie un essai de pénétration statique au cône à pointe mécanique (CPTM), y compris les exigences relatives au matériel, l'exécution et le procès-verbal. Les résultats de cet essai géotechnique sont particulièrement adaptés à la détermination qualitative et/ou quantitative d'un profil de sol — associés à des reconnaissances directes — ou pour être comparés à d'autres essais réalisés in situ.
Les résultats d'un essai de pénétration statique au cône peuvent, en principe, être utilisés pour évaluer la stratification, le type de sol et les paramètres géotechniques, tels que la densité du sol, les paramètres de résistance au cisaillement et les caractéristiques de déformation et de tassement.
L'ISO 22476-12:2009 spécifie le type d'essai de pénétration statique au cône; la classe d'application; la longueur ou profondeur de pénétration; l'altitude de la surface du sol ou de la surface du sol sous-marin, par rapport à un système de référence, à l'endroit où est réalisé l'essai de pénétration statique au cône; et la position du lieu d'essai de pénétration statique au cône par rapport à un point de référence fixe reproductible.

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.
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.
