GGU-UNDERPIN: Classical water pressure approach
Classical water pressure approach
For in-situ concrete walls, water pressure can affect the active and passive sides of the wall. The classical water pressure approach is illustrated in the following figure:
Figure 3 Classical water pressure approach
However, the classical approach does not take the permeability of the soil into consideration. The gradients on the active and passive sides are obtained by assuming a linear reduction in pressure around the wall.
