With the input from the section on slide safety, the moment, the horizontal force and the vertical force in the base is calculated, and with this the bearing capacity safety factor. The friction angle, the cohesion and the weight below the base 
2 are taken as the mean of the soils in the foundation joint of the wall. If several layers are present, the increases or reductions in bearing capacity resulting from this are not taken into consideration. If necessary, you can determine the bearing capacity safety factor using slip circle calculation.
With regard to the 
2 value, you can specify whether analysis is performed using the wet unit weight or the buoyant unit weight by going to the menu item "Nail wall/Preferences" and activating the "gam2 as buoyant unit weight" check box in the "Bearing capacity and sliding analysis" group box. If the soil properties in the ground deviate from the automatically determined mean values, it is also possible to employ user-defined soil properties.
