Cohesionless

The following properties are available for cohesionless soil layers:

• Angle of Internal Friction, Φ
• Angle of Friction Between Shaft and Soil, δ
• Coefficient of Lateral Earth Pressure for Shaft, K
• Unit Cylindrical Shear Limit

For more information, see Helical Pile Capacity Theory Manual.

To enable the inputs for Angle of Friction Between Shaft and Soil and Coefficient of Lateral Earth Pressure for Shaft, the user should tick the checkbox for Include Shaft Adhesion/Friction from the Capacity Calculations tab of the Project Settings.

The Unit Cylindrical Shear Limit provides an upper bound to the results of cylindrical shear and values shall not exceed this amount. The default value is set to 10000 so as to not preemptively cap the results at the limit.
