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
  

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.
