| Summary: |
This paper presents the investigation result of the application of lime-column (LC) technique
on expansive soft clay. The research studied the strength distribution surround the installed lime-column in
the radial and vertical direction from the center of column. In this research, the LC was designed as single
column with 50 mm in diameter (D), and the depth was 4D (= 200 mm). The soil strength surrounds the LC
is determined by unconfined compression strength (UCS) test and static cone penetration (CPT) test. The
test results show that the LC contributes to enhance the soil strength in radial direction up to 4D from the
center of LC. Higher strength occurs near the LC and decreases with the distance from the LC center. It was
also observed that soil strength tends to increase with time. The CPT results also showed that the installation
of LC affected the soil strength to a depth of 4xD beneath the bottom of LC. This research also confirms that
after installation of LC the water content of soil decreased near the LC, but beyond the distance of 4D in radial
direction the water content remained its original value. |
