Abstract

Collapsible soils, in their natural state, are stiff and strong. However, when they become wet these soils lose their strength and settle significantly. This settlement can damage highways and structures built over these collapsible soils. Deep dynamic compaction (DDC) is a method used for improving soil conditions by repeatedly dropping a very large tamper onto the ground from heights typically ranging from 50 to 100 ft. DDC has been shown to significantly increase the strength and stiffness of collapsible soils. However, vibrations caused by dynamic compaction may affect surrounding buildings.
