The Application of the Temped and Enlarged Pile Without Pile Shoe in Complex Geology Condition

This paper states the pile forming process and special advantages of the temped and enlarged pile without pile shoe,its appropriate conditions and the design calculating principle.Meanwhile the paper shows by practical example of engineering that the temped and enlarged pile without pile shoe is a new type pile which has reliable technology performance,obvious social and economic benefits.So it is worth extending and using widely.
