Abstract

various innovative foundation techniques are being used to stabilize and to improve the properties of the soft soil. Mixing with additives such as lime and cement are widely used and clay soil can be effectively stabilized with the help of lime. The present paper investigates the effect of lime column when installed in soft clay. A single lime column of specific diameter and depth was installed in a steel tank of specific dimensions filled with Kuttanadu clay. Soil sample was collected after specific days of curing from different radial distance from the center of lime column. The samples collected were tested for determining moisture content, UCC strength, liquid limit, plastic limit, shrinkage limit and coefficient of permeability. The value of moisture content and liquid limit decreased with ageing near to the lime column. The value of UCC strength, plastic limit and shrinkage limit increased with ageing near to the lime column. The values of coefficient of permeability initially increased near the lime column and after ageing the values were found to be decreased. The tests show that after the installation of lime column the lime will migrate up to a distance of 3D and with ageing there is alterations in the properties of the soil. As the radial distance increases the values of above properties remain more or less the same value as that of virgin clay.
