Comparison of the Behaviour of Dense Carbonate Sediments and Silica Sand in Cyclic Triaxial Tests
Comparisons are made between the behavior of two carbonate sediments and a silica sand subjected to cyclic axial stress applications under triaxial test conditions. The generated excess pore pressures and axial strains have been measured and the effects of varying the cyclic deviator stress, mean deviator stress level, and consolidation stress ratio have been examined. The pore pressure response is analyzed, using the failure envelope to determine the limiting excess pore pressure that the soil can sustain at a specified effective mean normal stress and deviator stress. By expressing the generated excess pore pressure as a fraction of the limiting pore pressure, it is shown that a more general characterization of cyclic loading effects under undrained conditions can be obtained. This ratio allows direct comparisons to be made between any two soils subjected to comparable test conditions.
