This 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 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. The following treatment methods are covered by this 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 annex A and B. The following treatment methods, among others, are not included in this 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; - dynamic compaction and other methods in which some form of treatment is applied to the ground surface; - explosive compaction.
