Influence of water

The water pressure along the joints and on the slip surface can be taken into account. It is introduced as external loading:

Water pressure on joints (water between blocks) Fv

It must be introduced into the analysis whenever the presence of water in the joints between blocks is expected. It is applied as a resultant force Fv in kN (the pressure acting on the immerse part of the joint per 1m run is considered).

Water pressure on the external slip surface (uplift pressure) U

It is defined as hydrostatic pressure on each slip surface of the polygon (external slip surface) separately and introduced as an external loading (uplift pressure) U in kN, which can be reduced depending on the slip surface permeability (the pressure acting on the immerse part of the slip surface per 1m run is considered).
