Abstract:

Following disastrous earthquakes in Alaska and in Nii(cata, Japan in 1964, Seed and Idriss developed and published the basic simplified procedure or evaluating liquefaction resistance of soils. The procedure, which is largely empirical, evolved over decades, until it has now established itself as the standard practice in North America and through- out much of the world. The purpose of this 1996 workshop was to convene a group of experts to review developments and gain consensus for further augmentations to the procedure. The scope was limited to evaluation of liquefaction resistance. Post-liquefaction phenomena, such as soil deformation and ground failure, although equally or more important were beyond the scope of this workshop. The participants developed consensus recommendations on the following topics: use of the standard and cone penetration tests for evaluation of liquefaction resistance; use of shear wave velocity measurements for evaluation of liquefaction resistance; use of the Becker penetration test for gravelly soils; magnitude scaling factors; correction factors Kl and KaX; evaluation of seismic factors required for this evaluation procedure. Probabilistic analysis and seismic energy considerations were also reviewed. Seismic energy concepts were judged to be insufficiently developed to make recommendations for engineering practice. Probabilistic methods have been used in some risk analyses, but are still outside the mainstream of standard practice.
