The effects of density change due to the explosive loading of nearly saturated granular soils are well known from field experience and explosive compaction has been efficiently practised for a long time as an economic deep ground improvement technique. At sites where strong dynamic excitation following the underground explosion is admissible, the explosive compaction of soil regions below the water-table level can offer an effective method of soil compaction. In the following paper the results of experimental studies of the explosive loading of soils are presented. From the combined interpretation of soil dynamic, geodetic and soil physics measurements, the main physical and technical characteristics of the explosive loading of water saturated soils are derived and important consequences for the practical application of the explosive subsoil remediation technique are pointed out.
