EN ISO 22475-1:2006

Geotechnical investigation and testing - Sampling methods and groundwater measurements - Part 1: Technical principles for execution (ISO 22475-1:2006)

ISO 22475-1:2006 deals with the technical principles of sampling soil, rock and groundwater, and with groundwater measurements, in the context of geotechnical investigation and testing, as described in EN 1997-1 and EN 1997-2.

Geotechnische Erkundung und Untersuchung - Probenentnahmeverfahren und Grundwassermessungen - Teil 1: Technische Grundlagen der Ausführung (ISO 22475-1:2006)

Dieser Teil von ISO 22475 legt die technischen Grundlagen für die Entnahme von Proben von Boden, Fels und Grundwasser und Grundwassermessungen im Rahmen geotechnischer Erkundungen und Prüfungen nach EN 1997 1 und EN 1997 2 fest.
Diese Erkundungen dienen:
a)   der Gewinnung von Boden- und Felsproben in einer Qualität, die es erlaubt, die allgemeine Eignung des Baugrundes für geotechnische Zwecke zu beurteilen und die geforderten boden- und felsmechanischen Eigenschaften im Labor zu bestimmen;
b)   der Feststellung von Folge, Dicke und räumlicher Lage der einzelnen Schichten, der Kluftsysteme und Störungen;
c)   der Feststellung von Art, Zusammensetzung und Zustand der einzelnen Schichten;
d)   der Feststellung der Grundwasserverhältnisse im Baugrund, Entnahme von Wasserproben für die Beurteilung der Wechselwirkung zwischen Grundwasser, Boden, Fels und Baustoffen.
Der Qualität einer Probe wird von den geologischen und hydrogeologischen Verhältnissen, von der Wahl des Bohrverfahrens und/oder des Probenentnahmeverfahrens sowie deren Ausführung und von der Handhabung, vom Transport und von der Lagerung der Proben beeinflusst.
Dieser Teil von ISO 22475 gilt nicht für Gewinnung von Bodenproben für landwirtschaftliche und umwelt¬bezogene Bodenuntersuchungen.
ANMERKUNG 1   Die Gewinnung von Bodenproben für diese Zwecke  wird in der Norm ISO 10381 behandelt.
Die Norm gilt auch nicht für die Gewinnung von Wasserproben zur Kontrolle der Eignung, Beschaffenheit und Erkennung von Wasserverunreinigungsquellen, einschließlich Ablagerung von Schlämmen.
ANMERKUNG 2   Die Gewinnung von Bodenproben für diese Zwecke  wird in der Norm ISO 5667 behandelt.

Reconnaissance et essais géotechniques - Méthodes de prélèvement et mesurages piézométriques - Partie 1: Principes techniques des travaux (ISO 22475-1:2006)

L'ISO 22475-1:2006 traite des principes techniques relatifs aux méthodes de prélèvement du sol, de la roche et de l'eau du terrain et aux techniques de mesurages piézométriques, dans le cadre des reconnaissances et essais géotechniques tels que décrits dans l'EN 1997-1 et l'EN 1997-2.
