I'm looking to estimate the constrained modulus (ksf) for use in the Janbu method for a hard dry clay that we were unable to extract brass cylinders for in the field during investigation. The clay was so hard that we could not drive the cylinders into the clay. Knowing that typical values for a stiff to hard clay at the upper end is around 60-70 ksf is there any literature or advice for estimating or quantifying the modulus of a very hard clay?
