Numerical Investigation on the Seismic Responses of the Menta Embankment Dam
Plane strain (2D) finite element method (FEM) simulations are performed in studying the seismic responses of the Menta embankment dam in Italy. An elastoplastic constitutive model is used to account for the static stress-strain behavior of the rockfill materials used, and a Hardin-type dynamic constitute model is employed to consider the dependence of the stiffness and damping on the mean effective stress and the cyclic shear strain amplitude. An empirical permanent strain model is incorporated into the traditional equivalent linear method to capture the earthquake-induced permanent deformation. The involved parameters are calibrated by fitting the available testing results or referring to those of similar materials. The stress and deformation within the dam after reservoir impounding, the acceleration responses during seismic excitation as well as the earthquake-induced permanent deformation are analyzed based on numerical simulations.
