Stiffness of Rock
Stiffness of Rock
(OP)
I am trying to model the response of a laterally loaded pile in rock, and to do this I need to know the modulus (E) and the spring stiffness (K) of the rock. I have information from load tests on the rock samples giving values for Uniaxial Compressive Strength. Is there any way of getting a reasonable estimate for E and K from this information?

All that said, relative to a latterally loaded pile, the rock is infinity stiff. The joints on the other hand are very soft. Therefore the performance of you pile will depend on the quality, not strength/E/k of the rock.
