Passive Pressure Calculation Considering Seepage
PROKON’s Retaining Wall Design module uses a simplified method in
calculating the passive pressure when seepage is incorporated in the analysis
of a retaining wall. PROKON’s simplified method used in the module calculates:
- The dry soil pressure for the height of the soil (H2) in front of the wall,
- Calculates an ‘effective’ hydrostatic pressure. Instead of adjusting the soil pressure
below the water table, the hydrostatic pressure is adjusted.
The above-mentioned is visually explained in the sketch below. For this
example, the following values were assumed:
calculation, refer to the following Knowledgebase article.
