Abstract

This study presents the results of dynamic compaction in loose, saturated granular deposits. The dynamic compaction operations were conducted by (a) the conventional method of Falling Weight Treatment (a.k.a. Deep Dynamic Compaction - DDC) and (b) the more recent Rapid Impact Compaction (RIC) method. The results of either soil improvement method are being presented, normalized and compared side by side in regards to the resulting soil improvement characteristics as well as the degree of efficiency with varying depth and location. Last, but not least, the improved mean soil compressibility parameters are validated through an embankment surcharge test.

Dynamic Compaction in Loose Granular Deposits; A Comparison Between Results from Conventional and Recent Improvement Methods

Chicago, Illinois

This study presents the results of dynamic compaction in loose, saturated granular deposits. The dynamic compaction operations were conducted by (a) the conventional method of Falling Weight Treatment (a.k.a. Deep Dynamic Compaction - DDC) and (b) the more recent Rapid Impact Compaction (RIC) method. The results of either soil improvement method are being presented, normalized and compared side by side in regards to the resulting soil improvement characteristics as well as the degree of efficiency with varying depth and location. Last, but not least, the improved mean soil compressibility parameters are validated through an embankment surcharge test.
