Geotechnische Erkundung und Untersuchung - Felduntersuchungen - Teil 1: Druksondierungen mit elektrischen Messwertaufnehmern und Messeinrichtungen für den Porenwasserdruck (ISO/DIS 22476-1:2005)

Dieses Dokument behandelt die Geräteanforderungen, die Durchführung und die Ergebnisdarstellung von elektrischen Druck- und Drucksondierungen mit der Piezospitze als Teil von geotechnischen Untersuchungen und Prüfungen nach EN 1997-1 und EN 1997-2.
Die Ergebnisse einer Drucksondierung werden verwendet zur Bewertung von:
-   Stratigraphie;
-   Bodenart;
-   Lagerungsdichte und Spannungszuständen in situ;
-   Mechanischen Bodeneigenschaften:
-   Scherfestigkeitsparameter;
-   Verformungs- und Konsolidationseigenschaften.
Innerhalb der elektrischen Drucksondierung und Drucksondierung mit der Piezospitze werden zwei Unterkategorien der Drucksondierungen betrachtet:
-   Die elektrische Drucksondierung (CPT) die die Messung des Spitzendruckes und der Mantelreibung einschließt;
-   Die Drucksondierung mit der Piezospitze (CPTU), die eine Drucksondierung mit zusätzlicher Messung des Porenwasserdruckes ist.
Der CPTU wird ausgeführt wie ein CPT mit der Messung des Porenwasserdruckes an einer oder mehreren Stellen an der Oberfläche der Sondierspitze
ANMERKUNG   Der CPT oder CPTU wird auch ohne die Messung der Mantelreibung benutzt.
Dieses Dokument spezifiziert die folgenden Eigenschaften:
a)   die Art der Drucksondierung, nach Tabelle 1;
b)   die Anwendungsklasse, nach Tabelle 2;
c)   die erreichbare Sondierlänge oder Sondiertiefe;
d)   die Höhe der Geländeoberfläche oder die Gewässergrundoberfläche mit Verweis auf eine Bezugshöhe;
e)   die Lage der Drucksondierung mit Bezug zu einem reproduzierbaren örtlich festgelegten Lagebezugspunktes;
f)   wenn möglich, die Methode der Wiederverfüllung der Drucksondierlöcher;
wenn möglich, die Tiefe und Dauer der Porenwasserdruck Dissipationsversuche.

ISO/CEN PARALLEL ENQUIRY
This draft International Standard is a draft standard developed within the European Committee for
Standardization (CEN) and processed under the CEN-lead mode of collaboration as defined in the
Vienna Agreement. The document has been transmitted by CEN to ISO for circulation for ISO member
body voting in parallel with CEN enquiry. Comments received from ISO member bodies, including those
from non-CEN members, will be considered by the appropriate CEN technical body. Should this DIS be
accepted, a final draft, established on the basis of comments received, will be submitted to a parallel two-
month FDIS vote in ISO and formal vote in CEN.
In accordance with the provisions of Council Resolution 15/1993 this document is circulated in
the English language only.
Conformément aux dispositions de la Résolution du Conseil 15/1993, ce document est distribué
en version anglaise seulement.
To expedite distribution, this document is circulated as received from the committee secretariat.
ISO Central Secretariat work of editing and text composition will be undertaken at publication
stage.
Pour accélérer la distribution, le présent document est distribué tel qu'il est parvenu du
secrétariat du comité. Le travail de rédaction et de composition de texte sera effectué au
Secrétariat central de l'ISO au stade de publication.
THIS DOCUMENT IS A DRAFT CIRCULATED FOR COMMENT AND APPROVAL. IT IS THEREFORE SUBJECT TO CHANGE AND MAY NOT BE
REFERRED TO AS AN INTERNATIONAL STANDARD UNTIL PUBLISHED AS SUCH.
IN ADDITION TO THEIR EVALUATION AS BEING ACCEPTABLE FOR INDUSTRIAL, TECHNOLOGICAL, COMMERCIAL AND USER PURPOSES, DRAFT
INTERNATIONAL STANDARDS MAY ON OCCASION HAVE TO BE CONSIDERED IN THE LIGHT OF THEIR POTENTIAL TO BECOME STANDARDS TO
WHICH REFERENCE MAY BE MADE IN NATIONAL REGULATIONS.
