| Abstract: | A one-dimensional wave propagation method for earthquake response analysis of horizontally-layered sites of infinite lateral extent is adapted to account for the finite cross-sectional dimensions of an embankment dam overlying a foundation deposit which may be considered infinite in its lateral extent. The procedure is used to study the response of an existing embankment dam for an actual earthquake record. A two-dimensional dynamic finite element analysis is also performed for this case. The records of ground acceleration at an outcropping base rock and at the crest of the dam are available for the site. The comparisons of computed and observed responses support the modified use of the simple numerical procedure. |
