Experimental and Empirical Modelling of the Relationship Between Specific Gravity and Shear Strength Parameters of Soils

The specific gravity of soil affects the strength, compressibility, and permeability of soils, likewise soils with low shear strength, which are more prone to slope instability, which can lead to landslides and other types of slope failure. An empirical model was developed which can accurately predict the specific gravity of different soils based on their shear strength parameters. The results from the experimental testing revealed a clear correlation between specific gravity and these shear strength parameters. This correlation suggests that the specific gravity of a soil sample can serve as a useful indicator of its shear strength characteristics. Higher specific gravity soils generally exhibited greater shear strength, and this understanding can be invaluable for engineers and geotechnical professionals involved in construction and infrastructure projects. The empirical model developed in this project can be used to predict the shear specific gravity of different soils based on their shear strength parameters, which can save time and costs in geotechnical investigations and design.
