Abstract

Liquefaction and dynamic properties of gravelly soils M.D. Evans Civil Engineering Department, Northeastern University, ^20 Snell Engineering Center, CASL4 ABSTRACT Liquefaction of gravelly soil has received much attention in recent years as several case histories have been reported where gravel and gravelly soil has liquefied. As a result, much research has been focused on assessing the liquefaction potential of gravelly soils both in situ and in the laboratory. Laboratory liquefaction assess- ment typically includes performing undrained, cyclic triaxial tests to determine liquefaction resistance and dynamic material properties. However, the potentially adverse effects of membrane penetration and compliance must be considered. Membrane compliance may result in pore fluid redistribution, soil densification, and increased liquefaction resistance in the undrained triaxial test, making it difficult to properly evaluate the performance of the protot
