Estimating Eu using Su for clay?
Estimating Eu using Su for clay?
(OP)
Hi guys,
I have been scratching my head off trying to find out the relationship between Eu (undrained Elasticity Modulus of soil) and Su (undrained shear strength of clay). However, literatures do not give a straight forward relationship between these two. Most of them are Eu=K*Su, but the K usually depends on various factors such as PI and OCR etc and can be read from charts.
I am wondering, say for normal consolidated clay, is there a simply relationship that I can determine Eu using Su??
Thanks,

The ultimate goal is to find out Kh (horizontal modulus of subgrade reaction), which is dependent on d, Eu and poisson's ratio based on Vesic (1961)'s elastic theory.
For clay with known undrained shear strength, using the formula above, Kh then can be determined.
So is there any correlation between Eu and Su ?
