摘要

This study depicts the experimental investigations into the effect of organic content on the shear strength and compressibility parameters of reconstituted soil. To these attempts, disturbed soil samples were collected from two selected locations of Khulna region. The reconstituted soil having organic content of 5-35 % were prepared in the laboratory to mix at various proportions of inorganic and organic soil at the water content equal to 1.25 times of liquid limits of collected samples .The usual procedure of preparation of soil slurry, deposition in a mold and application of surcharge were used to reconstitute sample. The mold diameter was 152 mm and height 222 mm and applied ultimate surcharge was about 60kN/m2. In the laboratory, ASTM (2004) methods were followed for the determination of strength properties and compressibility parameters of reconstituted soil at varying organic content. Here, it can be depicted that organic content significantly influence the shear strength and compressibility parameters of reconstituted soils. Moreover, some important correlations were developed based on strength and compressibility parameters and organic content which can be expressed by equations that may be proposed to estimate the various properties of soil of Khulna region using its organic content.
