Abstract

Test results show that the previously used linear relationship between the unit membrane penetration and logarithmic effective confining pressure has limitations at low confining pressure. An alternative method is described, based on a hyperbolic type of curve fitting, which can provide more suitable membrane penetration correction curves for various initial confining pressures. An example is given of triaxial strain path test results corrected using both the logarithmic and hyperbolic methods.
