OVERVIEW OF THE LIQUEFACTION ASSESSMENT AND SEISMIC STABILITY OF DUNCAN DAM - SPECIALTY SESSION, 46TH ANNUAL CANADIAN GEOTECHNICAL CONFERENCE SASKATOON, SASKATCHEWAN, SEPTEMBER 27-29, 1993

This overview introduces a series of six papers describing the approac h taken in a recent dam safety study to evaluate the liquefaction pote ntial and deformation behaviour for the current seismic setting of Dun can Dam. The dam was originally designed and built in the mid-1960s an d is an embankment structure founded on a thick sequence of glacial se diments. The papers were initially presented by a team of B.C. Hydro a nd their consultants at a specialty session held at, the 46th Annual C anadian Conference in Saskatoon in September 1993. The papers provide an excellent summary of the current state of practice in evaluating li quefaction and post-liquefaction behaviour.
