| Abstract: | To evaluate the bearing capacity and settlement behavior of the bored piles socketed in weak rock ground of Dongjiang River Bridge,two long and large diameter bored piles of the Bridge were tested in field by the technique of self-balanced static loading and the bearing capacity of the piles was well recognized.On the basis of the test,the characteristics of deformation of the type of the piles with the increase of loading and sustained compaction of slag under the toes of the piles are also studied. |
