Anchor Pile Definition:
Anchor piles are required to resist lateral loads with or without being braced depending on circumstances and an ordinary or standard house pile is required to carry a vertical load. The Anchor pile is used in a more critical application and therefore the strength characteristics have much greater values associated, compared to that of an Ordinary pile.
Below are excerpts from NZS 3605: 2001, offering a brief understanding of the strength values and generalised requirements of an Anchor pile.
