Experimental Study on Vertical Bearing Capacity of Post-grouting Bored Pile
In order to optimize the bearing capacity of bored pile,this paper takes a construction project in Fujian as an example to test and an-alyze the vertical bearing capacity of post-grouting bored pile.The results show that the ultimate displacement of pile top and ultimate bearing capacity of pile top are reduced by 30%and 13.9%after grouting treatment.The end pressure,end resistance and side resistance of post-grouting bored pile are 1.9 times,1.86 times and 1.2 times of that of ungrouting bored pile.The results show that grouting technology can ef-fectively improve the bearing capacity and side resistance of bored pile,reduce the settlement of bored pile,and effectively improve the bearing performance of bored pile.
