Abstract: In the excavation supporting system involving with tensional anchored piles, the pile bounding length determination is still a research topic. There is no general consensus in the engineering practice although several bounding length estimation methods are available. No national or industrial design code adopts the bounding length estimation method. This paper proposes a new simplified method of estimating the bound length of tensional anchored piles. The predicted results have been used in a project.

Key words: Tensional anchored piles, Bounding length, Simplified method
