Massive Rock

A model for p-y curves for drilled shafts socketed in massive rock was developed by Liang, Yang, and Nusairat (2009).

The following input parameters are required for the Massive Rock model:

• Uniaxial Compressive Strength
• Geological Strength Index (GSI)
• Intact Rock Constant (mi)
• Intact Rock Modulus (Ei) OR Rock Mass Modulus (Erm)
• Poisson Ratio
