摘　　要：机场项目属于国家大型基础建设项目,对地基施工质量的要求严格。部分机场建设项目场地的地基为杂填土,该类地基通常具备疏松、抗剪强度低、压缩性高等特点,如果不给予有效加固,将难以保证地基稳定性,从而影响后期飞机运行安全。文章结合具体工程案例,通过分析压密注浆法施工原理及压密注浆施工质量的影响因素,重点探讨压密注浆法处理杂填土在机场特殊环境中的运用,以期为机场地基施工提供参考。The airport project is a large-scale national infrastructure project,and has strict requirements on the quality of foundation construction.Some airport construction projects belong to miscellaneous landfill foundation,and such foundation usually has the characteristics of looseness,low shear strength and high compressibility.If no effective reinforcement is given,it will not be able to guarantee the stability of the foundation,thus affecting the safety of aircraft operation in the later period.Combined with specific engineering cases,this paper analyzes the construction principle of compaction grouting method and the influencing factors of compaction grouting construction quality,and focuses on the application of compaction grouting method in the treatment of miscellaneous landfill in the special environment of the airport,so as to provide references for airport foundation construction.
