Environmental factors can have a significant impact on the shear strength characteristics of soil. The ability of soil to withstand internal sliding is known as shear strength, and it is a crucial engineering characteristic. It is necessary to have a basic understanding of this aspect for stability analyses in geotechnical engineering, such as those involving foundations, cutting slopes, or earth dams. In this study, the shear strength parameters (c and Ф) of soil were examined by testing disturbed soil samples with different densities and water contents to mimic field conditions. The Digital Direct/Residual Shear apparatus was used to perform the shear strength test. The test results revealed that increasing soil density also increases its shear strength. Although the water content of the soil has a significant impact on its cohesiveness, it has no effect on its angle of internal friction.

Keywords: environmental, soil, shear strength, disturbed soil sample, cohesion, water content.
