      <title>DYNAMIC COMPACTION OF LOOSE GRANULAR SOILS: EFFECT OF PRINT SPACING</title>
      <link>https://trid.trb.org/View/408863</link>
      <description><![CDATA[Dynamic compaction is a soil improvement method in which a high-energy impact is used to densify loose granular soils.  The recent development of a wave-equation model enables a rational selection of the following operational parameters:  pounder weight, drop height, number of drops per pass, and number of passes.  The spacing between compaction points (print spacing), however, cannot be determined by this model.  This paper evaluates the wave-equation model and examines an approach to predict the lateral extent of soil improvement around the pounder.  Two examples of the procedure to evaluate the effect of print spacing are presented and three reported case histories of dynamic compaction projects are analyzed.]]></description>
