    Abstract

    An evaluation of the effect of time to failure on the measured pore pressures and effective stresses in consolidated undrained and drained triaxial tests on clays from Western Canada has been conducted. The results indicate that the test technique and volume change characteristics of the pore pressure measuring system has a marked effect on the pore pressures measured in consolidated undrained tests. The angle of internal friction in consolidated drained triaxial tests increases with times to failure up to 25,000 min.
