Execution of special geotechnical works - Ground treatment by deep vibration; German and English version prEN 14731:2026
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.
