| Abstract | Lime column Stabilization technique is a relatively new introduction to civil construction. This technique involves se of lime mixed and inserted in soft soils in column formation in similar manner to that for sand drain applications. This technique has been applied extensively in Sweden and Norway at a relatively low cost input. However, this technique has not been in common use in other countries simply because of lack of sufficient data in those countries. The present study was an attempt to simulate field conditions on the laboratory scale to study the effects of lime column method on Bangkok soil and consequently determine its applicability on Bangkok soil. consequently, an experimental investigation was carried out on soil from two different locations in Bangkok and the compressibility, settlement and strength characteristics were determined. In general, the influence of sample size, diameter of lime columns and the curing period of the lime-soil mix on compressibility and strength characteristics was studied. The compressibility characteristics were determined using Rowe cell of 6" diameter. The Rowe cell results were compared with the standard oedometer test results to highlight the effects emanating from sample size. Strength characteristics were found using a Laboratory Vane Shear testing machine of 6" diameter samples with 1" and 2" diameter lime columns at 1 day, 7 days, 21 days and 28 days curing period. The results of these tests showed that the lime columns had very significant effects on both strength and compressibility. The samples experienced less settlement and considerable strength gain depending upon the column diameter as well as the curing period. The 6"diameter samples showed lower compressibility than the 3" diameter samples and the results obtained using larger sample were more consistent. This study was the first attempt to represent field conditions in the laboratory and on the whole the results appeared encouraging. |
