The frame "Rock" allows us to input the length of the pile fixed into rock l [m] and rock bearing capacity R [MPa].
The rock is only modeled as elastic material, and no passive limit pressure is considered - contact stress can reach any values. In the frame "Analysis" the program checks if maximum stress does not exceed design rock bearing capacity. The active pressure of the rock is not considered.
Note: In many cases, the slip surface follows the rock subsoil. This case should be always investigated.
