undrained young's modulus of soft clays

[lvkb]

Can anyone give me a typical value of the undrained young's modulus (Eu) for very soft alluvial clays with an undrained shear strength of about 10kPa? Or is there a way I can estimate it from the results of an undrained triaxial compression test results?

I'm trying to calculate the immediate settlement of a rock embankment on such a material.

Thanks!
