摘要

Earthfill dams are geostructures which may be especially affected by seismic loadings, because soil skeleton that form them suffers remarkable modifications in its mechanical properties, as well as flow of water through their pores, when subjected to vibrations. The most extreme situation is the dam failure due to soil liquefaction. The application of a fully coupled endochronic based numerical model, developed and validated by the authors, to a set of theoretical cross sections of earthfill dams with impervious core, is presented. All these dams are same height and have the same volume of impervious material at the core. The influence of the core location inside the dam on its response against seismic loading is numerically explored. The analyzed theoretical dams are previously designed as strictly stable under static loads. As a result of this research, a design recommendation on the location of the impervious core is obtained for this type of earth dams, on the basis of the criteria of minor liquefaction risk, minor soil degradation during the earthquake and minor crest settlement.
