| Abstract: | Based on site tests of the reinforced concrete slurry bored pile, and the post grouting pile for Wufenganqu bridge in Qing-yin express highway , this paper analyzes the development of the lateral resistance and the end resistance, and the bearing properties for both piles. The technique of post-grouting has better bearing properties of piles, can improve the load bearing capacity and reduce the settlement. |
