摘要
The technical advantages of post-grouting for bored grouting pile are shorter length of pile, the bearing capacity improvement, less number of piles, good quality of pile foundation and the cost saving. Based on the engineering cases, this paper described the consolidation mechanism of compound post grouting for the end and the side of the pile, the empirical formula of bearing capacity, controlling points and controlling measures.oft-com:office:office" />
