摘要：Due to different soil strengths, drilled bored piles and slurry-supported bored piles affect the side friction. Through the application of post grouting technology, the friction resistance and bearing capacity of piles can be improved. In this paper, an analysis was conducted on the strength increasing rule of the side drilled bored hole and the side slurry-supported bored pile after post grouting at different ages, by means of chemical reinforcement. The results show that: the post grouting technology has better effect on the slurry-supported bored piles, especially in poor ground conditions, and that the strength on the 120^th day can be used as the design strength. Our research achievements can provide a theoretical basis for the post-grouting technology in engineering work.
