GGU-UPLIFT: Buoyancy safety using global safety factors

The buoyancy safety for each soil layer is determined via a comparison of the soil weights to the water pressures at the respective layer bases. Friction forces are not considered.

  • image-20241024-085306.pngN = buoyancy safety of layer N
  • Gi = self-weight of layer i
  • PN = water pressure at base of layer N
  • layer 1 (i = 1) is the uppermost layer

The minimum value of allimage-20241024-085325.pngN is the buoyancy safety of the system.
