GGU-UPLIFT: Utilisation factor (hydraulic failure) using partial safety factors

Using the partial safety factor concept the following must be verified:

  • S'k = characteristic flow force on the percolated soil mass

  • γH = partial factor for the flow force in favourable or unfavourable subsoil in the
    HYD (EC 7) limit state

  • G'k = characteristic dead load of the buoyant percolated soil mass

  • γg,stb = partial factor for stabilising permanent actions in the
    HYD (EC 7) limit state

  • layer 1 (i = 1) is the uppermost layer

The so-called utilisation factor µ can also be calculated from this relationship.

  • µN = utilisation factor of layer N

Utilisation factors ≤ 1.0 mean that sufficient safety is given.
