Abstract
Modification of weak soils can be accomplished by dropping a heavy weight onto a ground surface. The mechanisms for improving the ground by this technology can be described as dynamic compaction, dynamic consolidation, or dynamic replacement. The importance of each mechanism at one site is dependent on soil conditions, impact energy, weight dimensions, etc. A case study presented herein demonstrates how each mechanism affects the treatment effectiveness of this technology. The selected site has a mix of cohesive and cohesionless soil layers. A pilot study was conducted before the construction program for the whole site. Evaluation of the treated ground by laboratory testing and in-situ testing indicated the improvement of soil properties.

Ground Modifications by a Combination of Dynamic Compaction, Consolidation, and Replacement
St. Louis, Missouri
Modification of weak soils can be accomplished by dropping a heavy weight onto a ground surface. The mechanisms for improving the ground by this technology can be described as dynamic compaction, dynamic consolidation, or dynamic replacement. The importance of each mechanism at one site is dependent on soil conditions, impact energy, weight dimensions, etc. A case study presented herein demonstrates how each mechanism affects the treatment effectiveness of this technology. The selected site has a mix of cohesive and cohesionless soil layers. A pilot study was conducted before the construction program for the whole site. Evaluation of the treated ground by laboratory testing and in-situ testing indicated the improvement of soil properties.
