Pengaruh Variasi Jarak Kolom Kapur dalam Stabilisasi Tanah Lempung Lunak pada Tinjauan Nilai Indek Pemampatan Tanah (Cc)
Abstract: Numerousbuildingslocated
in north area of Java Island encountersettlement problem. The settlementoccurs
because most ofsoil in the areais soft clay soil. The behavior of this soilis
characterized by the large value of coefficient compression (Cc) and small
valueof bearing capacity. This condition causes potentially great consolidation
settlement. In this research, limes column stabilization method will be applied
to make soft clay soil better. Limes columns were expected to reduce Cc value
therefore consolidation settlement decreases. This research was conducted
throughlaboratory experiment, usingbox100 cm in lengths, 40 cm in wide, and 40
cmin height. Three variations of diameters (5 cm, 10 cm, 15 cm) and three
variations of distance of sample taken from outside of the limes column mould
(10 cm,20 cm, 30 cm) was applied in this research. Influence of limes column to
the value of Ccwasexamined. The result of this research showsthat limescolumn
couldsignificantlyreduceCcvalue. TheCc valuedecreases when thedistance of
sample taking placedecreases. The average of Ccdeclineon three
variationsdistance of column (10 cm, 20 cm, 30 cm)are 17.28%, 44.97%,
52.24%respectively. The most efficient distance of thelimes column is 20 cm.
