Abstract
Prior to 1970, the majority of earth and rockfill dams were constructed with little regard for earthquake resistant design- especially in the Pacific Northwest which, at that time, was considered an area of low to moderate seismic activity. Since the early 1970's, and in particular since the near-catastrophic failure of the Lower San Fernando Dam in 1971, the vulnerability of hydraulic fill dams to pore pressure build-up and loss of strength as a result of earthquake shaking is well documented. In contrast, very few case histories exist on the liquefaction susceptibility of saturated gravel filters in zoned embankments. This paper summarizes a detailed finite-element, seismic stability analysis for a dam which has a saturated gravel filter of unknown relative density under the entire downstream shell of the embankment.
