Abstract:

This paper outlines a procedure for evaluating liquefaction resistance of soils using shear wave velocity measurements. The procedure follows the general format of the Seed-Idriss simplified procedure based on SPT blow count. It was developed following suggestions from industry, researchers, and practitioners, and using case history data from 26 earthquakes and over 70 measurement sites in soils ranging from sand to sandy gravel with cobbles to profiles including silty clay layers. The procedure correctly predicts moderate to high liquefaction potential for over 95% of the liquefaction case histories. A case study is provided to illustrate the application of the proposed procedure.
