Ditch Bottom Verification

Standard verification of heave and piping is performed only in case of hydrodynamic pressure when the heel of a structure is sunk into a permeable subsoil, which allows a free water flow below the structure. This checks follow EN1997-1 standard.

Verification of ditch bottom according to Chinese standards (e.g. upheavel according to Prandtl slip surface or effect of the confined aquifer) is available for all types of GWT. These checks are not standardly required and they are available only when using analysis according to Chinese standards.
