The soil parameters needed for a theoretical analysis of the behavior of pile foundations are the stiffness and the strength. Because soil behavior is strongly non-linear, with the stiffness and the strength being dependent upon the actual stress, it may be useful to use parameters which take into account the non-linear effects. For axially loaded piles the quake is proposed for the characterization of the soil stiffness. This quantity is widely used in dynamic analysis of piles, and has the advantage that it automatically includes the increase of stiffness with depth. For laterally loaded piles a similar quantity can be introduced: the stroke. It is also shown that the lateral flexibility of piles is mainly dependent on the strength of the soil, and not so much upon its stiffness.
