Add a deep foundation to record its inputs, capacity and governing check.

Learning objectives

  • Compute skin friction and end bearing
  • Design pile groups
  • Check lateral capacity

Engineering judgment

  • Group efficiency reduces capacity.
  • Downdrag can reverse the sign of skin friction.

Governing standards

  • NAVFAC DM-7

    Soil Mechanics and Foundations

    Bearing capacity, earth pressure, slope stability
