GWT + NSF
The"GWT" ("GWT + NSF") serves to specify the depth of ground water table and the level of incompressible subsoil.
The values can be edited either in the frame by inserting values into input fields, or on the desktop with the help of. The GWT changes the in the soil profile.
The incompressible subsoil cuts off the influence zone below foundation. It also influences a reduction of the settlement.
Frame "GWT" - without influence of NSF
If the option "Consider influence of negative skin friction" is set in the frame "", then it becomes possible to enter parameters of the negative skin friction using the "GWT + NSF" frame - boundaries of the region, where the influence of is considered, or sliding region and its material and cohesion.
