Abstract

The main objective of this work is to investigate the effect<br>of sand-gravel compaction piles on the behavior of loose<br>sand deposits. Reduced model tests were carried out on<br>an artificial sand deposit filling a trench 1.5 m wide, 3.0 m<br>long and 2.5 m deep, excavated in a clay rich soil. In situ<br>geotechnical tests and DC electrical resistivity<br>measurements were carried out before and after the<br>construction of compaction piles, in order to characterize<br>the changes in the sand deposit. Conductivity anomalies<br>were observed in the position of the compaction piles with<br>better performance. These anomalies are caused by the<br>introduction of the sand-gravel compaction piles and<br>possibly more related to the mineralogical composition of<br>these piles than compaction itself.
