| Title | Execution of special geotechnical works - Ground treatment by deep vibration |
| Work Item Number | 00288013 |
| Abstract/Scope | his European Standard is applicable to the planning, execution, testing and monitoring of ground treatment by deep vibration achieved by depth vibrators and compaction probes. The following types of treatment are covered by this European Standard: deep vibratory compaction to densify the existing ground; vibrated stone columns to form a stiffened composite ground structure by the insertion of granular material which itself shall be densified. Generally, stone columns have a diameter greater than 0,6 m and lower than 1,2 m. The following treatment methods are covered by this European Standard: methods in which depth vibrators, containing oscillating weights which cause horizontal vibrations, are inserted into the ground; methods in which compaction probes are inserted into the ground using a vibrator which remains at the ground surface and which in most cases oscillates in a vertical mode. Treatment methods are outlined in Annexes A and B. The following treatment methods, among others, are not included in this European Standard: methods in which sand or stone columns are installed by means of impact or top vibratory driven casing; methods in which very stiff columns are formed either by the addition of cement to granular material or by the use of concrete or any other binder; dynamic compaction and other methods in which some form of treatment is applied to the ground surface; explosive compaction. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
In the case of undated standard, a link to the last dated version is provided.
In the case of series, a link to each standard identified in the series is provided.
We also invite you to check (via the website) whether corrigenda and/or amendments shall be read in conjunction with the main standard.
