Parametric Study of the Effects of Seismic Strength Degradation of Fine Grained Soils Beneath Highway Embankments and Bridge Abutments

This will be a series of parametric studies to evaluate the effects of strength loss during earthquakes on typical highway embankments and abutments. The parameters to be studied are: the height and geometry of the embankments; the initial strength of the foundation soils; the strength loss during ground shaking. The results of this study will illustrate the significance and potential impacts of strength loss of fine grained soils during earthquakes. The study may lead to improved design of embankments and abutments in seismic zones.
