Abstract

The paper aims to evaluate the stability of a particular section of the Buriganga River embankment, which is an economically significant river in Bangladesh. The study involved collecting soil samples from the embankment to determine its index properties, grain size distribution, organic matter content, and shear strength parameters. Laboratory tests, including direct shear and consolidated drained shear tests, were conducted with varying water content and normal load to determine the cohesion and angle of internal friction for both disturbed and undisturbed soil samples. Using XSTABL software, slope stability analysis was performed with a 1:1.5 slope based on the soil investigation results. The maximum factor of safety was found to be 1.548 for the undisturbed soil sample and 0.82 for the disturbed soil sample. The study showed that increasing soil cohesion significantly increases stability.
