Geotehnično preiskovanje in preskušanje - Preskušanje na terenu - 5. del: Preskus s podajnim dilatometrom v vrtini (ISO 22476-5:2012)

Ta del standarda ISO 22476 določa zahteve glede opreme, izvajanja preskusov s podajnim dilatometrom v vrtini ter poročanja v zvezi z njimi. Ta del standarda ISO 22476 se uporablja za preskuse v tleh, ki so dovolj trdna, da vrtanje nima negativnega vpliva. Ta del standarda ISO 22476 se uporablja za štiri postopke za izvajanje preskusa s podajnim dilatometrom v vrtini. Ta del standarda ISO 22476 se uporablja za preskuse, ki se izvajajo v globini do 1800 m. Preskušanje lahko poteka na kopnem ali na morju.

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.
ISO 22476-5 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 341, Geotechnical investigation and testing, in collaboration with Technical Committee ISO/TC 182,
Geotechnics, Subcommittee SC 1, Geotechnical investigation and testing, in accordance with the Agreement
on technical cooperation between ISO and CEN (Vienna Agreement).
ISO 22476 consists of the following parts, under the general title Geotechnical investigation and testing —
Field testing:
— Part 1: Electrical cone and piezocone penetration tests
— Part 2: Dynamic probing
— Part 3: Standard penetration test
— Part 4:Ménard pressuremeter test

Introduction
The results of dilatometer tests are used for deformation calculations provided that the range of stresses
applied in the test are representative of the stresses to be applied by the proposed structure. Loc
