BS-Theory: Bounded surcharges (active side)
Up to 40 bounded surcharges can be positioned at any height on the active side.

The earth pressure coefficient k is acquired from kah for active earth pressure and from k0 for at-rest earth pressure. If this option is activated, the resulting earth pressure is then redistributed.
If negative values are entered, e.g. to generate a double-bounded surcharge, the linear component between φ and ϑ may not be adopted.
