Soil/Bedrock Spring Modulus

Soil/Bedrock Spring Modulus

Soil/Bedrock Spring Modulus

(OP)
Does anyone have a reference which provides typical soil spring modulus for soil and bedrock? I need to provide some information to a structural engineer for some drilled shafts in bedrock.

I've found vague information about the Winkler theory (?), but haven't found any numbers.

Thanks for any help.

Vertical or lateral?

RE: Soil/Bedrock Spring Modulus

(OP)
Lateral loads.  The structural engineer is using a triangular distribution of a lateral load applied at the top of the shaft and needs a spring modulus for the bedrock.

RE: Soil/Bedrock Spring Modulus

go and search as Novak. He provided a group of impedance functions for shallow and deep foundaions.
