Seismic analysis and design of asphaltic concrete core embankment dams

Studies on the response of an embankment dam and the behavior of asphaltic core were described using a nonlinear elastoplastic model. Results were compared with an equivalent linear approach using the traditional Newmark method. Static and dynamic analyses were carried out using finite difference code, and the program was adjusted to include the appropriate hyperbolic soil model in the static case and linear method in the dynamic case. Results indicated that large differential settlement occurred between the core and surrounding transition material, and Newmark-based method showed extensive cracking of the core.
