Estudo da compactação do solo por meio de ensaios geotécnicos e de métodos

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