Abstract
The seismic design of earthfill and rockfill dams routinely relies on methods of analysis, which adopt simplifying assumptions regarding the dam geometry, soil behaviour and the dynamic interaction of the fluid and solid phases within the dam body. This paper explores such simplifying assumptions, which are typically used for the numerical modelling of earthfill and rockfill embankment dams, within the context of two case studies. First a clay core dam, the La Villita dam in Mexico, is considered focusing mainly on the implications of 2D plane strain approximation in the case of dams built in relatively narrow canyons. In the second case study, of the rockfill Yele dam in China, the importance of hydro-mechanical coupling is explored by parametrically varying the permeability of the materials.
