Execution of special geotechnical works - Ground treatment by deep vibration
Abstract
This document establishes general principles for the execution of soil treatment by deep vibration. The following types of treatment are covered by this European Standard: — deep vibratory compaction to densify the ground; — vibrated columns formed by inserted granular material laterally/radially compacted against the surrounding ground to form a stiff composite column-soil structure (vibrated compacted granular columns); — vibrated columns formed by inserted material developing unconfined compressive strength comprising a composite of binder and granular material (rigid columns). 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 above ground surface, and which oscillates in a vertical mode. The following treatment methods are not included in this European Standard: — dynamic compaction, dynamic replacement and other methods in which some form of treatment is applied to the ground surface; — uncompacted granular columns primarily used as drains; — explosive compaction.
