"Square"and"Circle"of Anchor Pile in Subgrade Retaining Structure
It is demonstrated the advantages and disadvantages of square pile and circular pile from the aspects of section resistance,pile-soil interaction mechanism,economic benefit and construction.The technology of forming square colum was improved and applied to three construction projects.The result shows that the anchor square pile used for slope support has its advantages in terms of mechanical performance and economy,but the construction method and construction equipment lag behind the circular pile.At the present,the hole forming technologies and mechanical tools of square piles have been in the development and application,and have more successful experience.Compared with circularpiles,square piles are still the first choice for slope support.
