| 摘 要： | 在介绍膜袋注浆桩及其加固机理的基础上,通过现场实体试验,对注浆过程中孔隙水压力变化进行了分析,并结合注浆量统计分析、现场开挖检验和钻孔抽芯检验对成桩状况进行了研究,结果表明直径为40cm的单个注浆孔挤土效应影响范围可达5m,在2m范围内挤土效应衰减较快,而注浆后可形成连续、强度较高的桩体。

| Abstract: | In this paper, on the basis of introduction in detail to the bag grouting pile and the reinforcement mechanism, through field tests, the changes of grouting pore water pressure have been analyzed; being combined with grouting quantity statistical analysis, the excavation inspection and core drilling test, studies have been performed, the results show that the effect range of soil compacting by single grouting of 40 cm in diameter can reach 5 m, the compaction effect decreases rapidly in 2 m range, and continuous piles with high strength have been made after grouting. |
