PERMANENT DEFORMATION ON PREEXISTING SLIDING SURFACES IN DAMS. DISCUSSION

A discussion of a paper with the aforementioned title by Gazetas and Uddin, published in this journal (Volume 120, Number 11, November 1994), is presented. Discusser Jansen states that in some embankments, a distinct preexisting slide surface like the authors' model may be difficult to detect and delineate because many dams undergo general deformation rather than well-defined displacement. Jansen offers the view that the complexity of seismic forces, as well as dam and foundation conditions at the time of an earthquake, cannot be represented precisely by numerical techniques, although they are necessary to assess potential behavior. Several sets of computations with varying parameters are advisable to cover the possible ranges of seismic loading and embankment and foundation response. No closure is offered by the authors.
