Come on Focht3, the original question was how to calculate settlements in unsaturated clay. Why would someone want to use saturated undrained soil properties for an unsaturated clay? As I mentioned before, saturated undrained modulus values should be higher upper bound values, i.e., less...
I think a 1-D compression test is an applicable method for estimating settlement in unsaturated clays. Unless local experience is already available, I would perform the test both unsaturated and with inundation to evaluate possible effects of inundation. It should be kept in mind that...
