The stability of the slope must be taken into account while planning and constructing retaining structures such as an earth dam and dyke. Slope failure can lead to disastrous consequences such as damage to life and property. The slope stability analysis using different available techniques, in which the finite element method is the best. In this study, the slope stability of an ash dyke is examined using finite element technique, using PLAXIS 2D model, under various construction and operational conditions namely, dry condition, submerged condition and earthquake condition. The evaluation employs the Mohr-Coulomb method to calculate the safety factor. The results of the model indicate that the displacement and deformation for the dry and submerged loading scenario is 0.4207 m and 0.2880 m respectively. According to the model's findings, the downstream faces and rock toes are the most vulnerable locations for failure of the dyke. The factor of safety is found to be 2.4 in the dry condition, while in submerged conditions, the factor of safety is observed to be 1.56. The results of the study show that since the FOS for both dry and submerged conditions are less than 1.5, the dyke is considered to be safe.
