Strain rates ranging from 20% to 100% per second were used in consolidated-undrained triaxial tests, to investigate the influence of rate effects on the behaviour of cohesive soils. To apply the required loading rates, a hydraulic test unit was designed. Techniques were developed for producing saturated remoulded samples and for measuring the applied stresses, strain and pore pressures in the dynamic test. Electrical instrumentation was used for sensing and recording the transients. No pore pressure measurements were obtained in the dynamic tests conducted. For the same consolidation pressure, the strength of samples as determined in a triaxial test increased with increasing strain rates. Rate dependent dilatational effects are not the predominant cause of the observed behaviour.
