GWT above toe of slope

Hydrostatic pressure, GWT above toe of slope

The slip surface is either entirely or partially below the ground water table, the maximal water pressure is at the toe of face.

Hydrostatic pressure on slip surfaceHydrostatic pressure on slip surface

The value of water pressure u at the heel of slope is given by:

where: γw - bulk weight of water
ht - height of GWT above toe of slope

The resulting compressive water force acting in the direction normal to the slip surface is given by:

where: γw - bulk weight of water
ht - height of GWT above toe of slope
α - deflection of slip surface from horizontal
