Abstract

The objective of this research is to the analysis of the different soil improvement techniques and the comparable model of these soil improvement techniques. In Bangladesh, different soil improvement techniques were used by different construction firms to improve the soil bearing capacity, but many of them could not verify the techniques after improvement. The verification of the soil improvement techniques is more important than the implementation of the soil improvement techniques. A comparison has been made between results obtained from three soft soil improvement techniques. Analysis of the effectiveness of soft soil improvement technique before and after improvement technique. From analyses, it has been revealed that for Tongi to Uttara along the Project package CP01 soft clay layer is effective for Sand Compaction Pile (SCP) and the sand layer, which is susceptible to liquefaction is effective for Dynamic Compaction (DC) method. After the improvement standard penetration test (SPT) value increases dramatically; this is a significant finding of this research.
