Active horizontal force acts behind the pile, and it is defined as follows:
- residual active force - the magnitude can be changed in the subsuquent stages
- active pressure
- input pressure distribution - the overall pressure on the pile above the slip surface is defined in the table, passive horizontal force is not defined anymore
Passive horizontal force acts in front of the pile, and it is defined as follows:
- residual passive force - the magnitude can be changed in the subsuquent stages or automatically calculated according to the excavation in front of the pile
Active and passive residual forces can be calculated in the "Slope stability" program and transferred into the program "Anti-Slide Pile". Next, the shape of the pressure distribution must be specified. Program does NOT INCREASE the input passive and active force by any partial factor during the analysis - it is necessary to determine them according to required standards and rules.
If the forces are obtained from the Slope stability program, they correspond with the way of analysis set in the program. For example, when an analysis is done according to Eurocode EN 1997-1, the received values are already design values of forces.
