I guess this equation is for the empirical calculations. Not for FEM or FDM! fHd[8{;P:

Normally, the pile is simpilified by beam element in plain strain condition in FEM. :EOai%i

Using the EI of pile divided by spacing with ignoring soil stiffness (because it is very small compared to concrete or steel pile). QdgJNT<=H,

BTW, if you really want to discuss something, please post the question or problem clearly, otherwise nobody can help you or discuss this.
