COST EFFICIENT SOFT SOIL IMPROVEMENT TECHNIQUE FOR A SPECIFIC PROJECT AT NAMAPARA, KHILKHET, DHAKA.

Abstract

This paper contains the cost efficient soft soil improvement techniques for a specific project at Namapara, Khilkhet, Dhaka. The objective of this research is to analyze the different soil improvement techniques and the comparable model of these soil improvement techniques. The verification of the soil improvement techniques is more important than the implementation of the soil improvement techniques. A cost comparison has been made between four soft soil improvement techniques. There are Sand compaction pile (SCP), Soil replacement compaction, prefabricated vertical drain (PVD) & Dynamic compaction (DC). Analysis of the effectiveness of soft soil improvement technique before and after improvement techniques. Application of those most common improvement techniques with cost estimating. After estimate we have find out that, SCP improvement technique is the most cost efficient (216.6 tk per sq ft) and easier technique to increase bearing capacity of soil. This is a significant finding of this research.
