Abstract

The conventional foundation systems are not suitable for the massive structures in Khulna region i.e. South-west part of Bangladesh because an organic soil layer exists at a depth 10ft to 25ft from the existing ground surface. The existence of organic soil layer in the deposits results excessive settlement due to its high compressibility and low shear strength. To overcome the problem, soil improvement techniques are usually adopted depending upon the type of constructions. It is necessary to know the degree of improvement for the different improved grounds prior to the selection of ground improvement techniques. So a laboratory investigation was conducted to find out the effect of improvement techniques on reconstituted organic soil to obtain a guideline for selection, design and construction of suitable soil improvement method for this region. The laboratory investigation reveals that the compacted sand bed improves bearing capacity of organic ground significantly.

Laboratory Investigation on the Behaviour of Improved Organic Soil of Khulna Region

Arlington, Virginia

The conventional foundation systems are not suitable for the massive structures in Khulna region i.e. South-west part of Bangladesh because an organic soil layer exists at a depth 10ft to 25ft from the existing ground surface. The existence of organic soil layer in the deposits results excessive settlement due to its high compressibility and low shear strength. To overcome the problem, soil improvement techniques are usually adopted depending upon the type of constructions. It is necessary to know the degree of improvement for the different improved grounds prior to the selection of ground improvement techniques. So a laboratory investigation was conducted to find out the effect of improvement techniques on reconstituted organic soil to obtain a guideline for selection, design and construction of suitable soil improvement method for this region. The laboratory investigation reveals that the compacted sand bed improves bearing capacity of organic ground significantly.
