| Abstract:In light of the characteristics of bored piles, the processes of improving the bearing capacity of boredpiles are summarized in this paper. The results of piles' tests in situ show that piles' performance are improved by toe pressuregrouting, this paper illustrates that the toe pressure postgrouting can be used both as a routing construction method, and as a reliable remedial measure. |
