| Abstract: | For the super-long bored piles,the development space is very limited by increasing the pile length and diameter to increase the bearing capacity of single pile.Tip grouting is an effective way to increase bearing capacity.This paper briefly introduced mechanisms with tip grouting to improve the bearing capacity and tip grouting construction notes.The tip grouting construction scheme were detailedly described in the paper. |
