ABSTRACT

A detailed study on dynamic deformation analysis of the upstream and downstream slope of the rockfill dam at the Nauseri Dam site is performed to address dynamic stability of the slope under the Operating Basis Earthquake (OBE), 475-year and Maximum Credible Earthquake (MCE). The dynamic deformation analysis in this computation package includes Newmark deformation analysis, Makdisiseed deformation analysis and Bray-Travasarou deviatoric slope displacement analysis. The site response analysis is carried out using GeoStudio 2012 QUAKE/W to predict motions propagating through slopes from the underlying bedrock. In this study, the deterministic methods developed by Newmark and Makdisi-Seed and the probabilistic method proposed by Bray and Travasarou were used to evaluate the dynamic deformation of the upstream and downstream slope of the rockfill dam. It is concluded that the estimated displacements of the upstream and downstream slope by two deterministic methods, such as Newmark and Makdisi-Seed while one probabilistic method that is Bray and Travasarou used are consistent and give better results compare to other methods.
