How to Use This Calculator
  1. Enter seabed soil parameters: undrained shear strength (kPa), friction angle (degrees), and submerged unit weight (kN/m3).
  2. Enter foundation width (m) and length (m).
  3. Read ultimate bearing capacity (kPa) from the Meyerhof or Hansen formula.
  4. Apply appropriate safety factors (typically 2.5-3.0) to get allowable bearing capacity.
  5. Verify pile tip resistance and skin friction contributions separately for pile design.
