Abstract

The liquefaction resistance of soils has been noted to be influenced by fines content. At present piezocone measurements are not capable of providing accurate predictions of fines content and are therefore open to uncertainty. The work presented herein, extends previous analyses of liquefaction resistance and develops the framework for prediction of liquefaction resistance through the CPT recovered parameter of excess pore pressure (u2 ) measured in flight. The main driving force behind liquefaction is the build-up of excess pore pressure in the soil structure; therefore the use of the piezocone measured excess pore pressure is a preferred variable to fines content in the analysis of liquefaction resistance.
