Abstract
Two pilot tests were conducted on two different areas to evaluate the effects of compaction columns on the engineering properties of a sand-clay layered soil profile. In the first field test, 120 stone columns were constructed using vibro replacement and casing-ramming techniques, in a equilateral triangular array with different spacing. In the second field test, 20 stone columns were constructed using casing-ramming technique, in a equilateral triangular array spaced 3m c/ c. In order to evaluate, the stone columns effectiveness and effects, both a detailed in-situ testing and instrumentation programs were planned to be carried out in five different stages. Results obtained from field tests suggest that compaction columns improve the engineering properties of both granular and cohesive soils.
