A Parametric Study of Slope Stability and Comparison of Breach Parameter for Different case of Earthen Dam

Abstract

The slope stability analysis of earthen dam for every aspect is very crucial because huge risk is related to dam at every stage of construction and working period. The very huge volume of water stored in reservoir by dam, which is very hazardous to downstream location for worst-case scenarios at time of breach in dam. Therefore, stability of dam and breach scenarios is very important to analyze for better solution for dam construction technique. Stability of dam depend upon stress occur in different loading condition, strength of material, geometric parameter, type of foundation and equipment installed. In this study, comparison of downstream slope stability by varying material property of dam and slope of downstream of dam. The effect of core seize, shape, inclination and position on stability of dam. Factor of safety obtained from limit equilibrium and finite element method are compared for various case of dam. In addition, dam break analysis is done for comparing the effect of different breach parameter equation on downstream breach flood. In breach analysis of dam, type of dam and failure mechanism of dam also effect downstream breach flood is also studied.
