The elastic pile foundation analysis by Poulos is well developed and has been adopted by some countries in their design guideline. In the vertical load analysis, the author has discovered that the approach by Poulos is sensitive to the number of segments used for analysis and can lead to some unreasonable results for pile in finite depth of soil. In the lateral load analysis, the group interaction factor which is claimed to be a linear relation of the departure angle β by Poulos is found to be a linear relation of sin2 β by the author.
