An analysis for new cast-in-site concrete piles such as DX pile,barrette,Y-shaped pile,thin-wall pile,is conducted from angles of section type,application field and construction technology,with their load-carrying behaviors studied.

Excavation of deep foundation pile is a frequently difficult technical problem related in municipal construction in recent years, especially the methods of excavation and measure of retaining in the excavation of soil layer of large aperture rectangle pile, which all lead a higher requirement to the excavation of deep foundation.
