| Summary: |
This lime-column technique has been applied successfully in recent years to improve the physical and
mechanical properties of the soils. This technique would increase soil bearing capacity and reduces
soil settlement owing to improving of soil strength and stiffness. This paper presents the preliminary
results of the small laboratory model test of lime-column technique on soft clay soil to investigate
load-settlement characteristic in laboratory. The lime-column was designed as single column with 50
mm in diameter (D), and the depth was 100 mm. The laboratory tests carried out was one dimensional
consolidation and small plate loading test. The test results show that before installation of the limecolumn,
based on the load-settlement curve, the mode of failure was likely defined as general shear
failure. The bearing capacity of the soft soil increased from 0.23 kN to 5.2 kN, it was about more than
20 times increasing, after the lime-column was installed. Whole results indicated that lime-column
technique is a valuable method to enhance soil bearing capacity and reduce soil settlement.
