Abstract:This study presents the results from a series of laboratory tests carried out on rammed aggregate piers (RAPs) installed in different clayey sand beds formed in a large scale model test tank. The clayey sand beds were prepared by mixing 60 % sand, 40 % clay at a water content of 1.5 times the liquid limit of the clayey sand. The slurry mixtures were allowed to consolidate one-dimensionally until they reach different undrained strength values (cu = 2.5, 3, and 10 kPa). The diameter and length of RAPs were in th… Show more
