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.
