As in the odometer test, the results of a triaxial test depend on the strain rate (rate dependence). An increase in the strain rate generally results in increased undrained strength and brittle behavior. Lunne and Andresen [37] suggest 150% increase in the undrained shear strength when the rate of shear is increased to very fast rate from a very slow rate. The experiences from Scandinavian soft clays shows that there is a little difference in undrained shear strength when the specimen are sheared at ratesbetween 0.7 and 3.0% per hour.
