Abstract

Soils display strain rate dependant behaviour which may pose a problem in geotechnical engineering applications. In this study a modified lectromechanical triaxial apparatus was used to shear normally consolidated reconstituted Speswhite kaolin samples over a range of strain rates from 1%/hr to 180,000%/hr. The purpose of the investigation was to explore the variation of rate dependant soil response to increased in both drained and undrained
conditions. Results show that the shear strength of the soil to be rate dependant at all of the strain rates investigated. In the case of a drained response overall strength decreased with increasing strain rate, with the rate effects displaying
strain level dependency. Where the response was undrained the soil achieved a greater strength with increasing strai rate which increased at a greater rate than the generally assumed 10% increase in strength per log cycle increase in strain rate.
