TESTS FOR SOIL CREEP

THE IOWA BORE-HOLE SHEAR APPARATUS, MODIFIED TO MONITOR TIME DEFORMATION BEHAVIOR IN SOILS, PRODUCED BOTH PRIMARY AND TERTIARY CREEP CURVES FROM IN SITU TESTS ON SOILS. SIMPLE LABORATORY SHEAR TESTS PRODUCED COMPARABLE RESULTS. AN EXAMINATION OF THE CONCEPT OF YIELD STRESS LED TO THE SPECULATION THAT TRUE YIELD STRESS IS ONE THAT PRODUCES SECONDARY OR LINEAR CREEP CURVES. THE SECONDARY CREEP CURVES ARE A TRANSITION BETWEEN PRIMARY AND TERTIARY BEHAVIOR. THE CREEP RATE FROM THE BORE-HOLE CREEP TEST BECAME SO NEARLY LINEAR THAT THE PSEUDO-BINGHAM YIELD STRESS COMPUTED FROM THESE TESTS IS CLOSE TO THE TRUE YIELD STRESS. /AUTHOR/
