The "New pile", or "Modify pile properties" dialog window serves to input the location of the pile (coordinates x, z, length of the pile l and spacing between piles b).
The "Locate to the terrain" button places the starting point of the pile head on the ground surface. Sometimes, an anti-slide pile can be located in mass directly (in this case, it's possible to analyze slope stability, but it's not possible to run the "Anti-Slide Pile" program).
Then, the pile cross section (circle - diameter of pile d, rectangle - dimensions sx, sy) and the pile parameters are specified - distribution of bearing capacity along the pile length (linear, constant), maximum bearing capacity Vu, gradient K and direction of passive force (prependicular to the pile, parallel to slip surface). All input parameters can be modified in the stage of construction, in which the anti-slide pile was introduced. In subsequent stages the anti-slide pile can only be removed.
Influence of anti-slide piles on the slope stability assessment is described in more detail in the theoretical part of the help. Other calculations of the anti-slide piles (analysis of internal forces, dimensioning of reinforcement of piles) are based on the analysis of active and passive forces in the "Anti-Slide Pile" program.
