摘　　要：文章结合孟加拉国某机场工程,从工艺试验、施工方法、安全措施、质量控制等方面,详细分析了挤密砂桩在机场工程中的应用情况。对土工管袋填砂施工方法进行分析和总结,堆载预压分期加载进行了研究,工程实践表明,堆载预压分两期加载效果良好,土工管袋填砂施工方法实用,在降低项目造价、缩短工期等方面优越显著,可为类似工程提供借鉴。Based on an airport project in Bangladesh,this paper analyzes the application of compacted sand piles in the airport project from the aspects of process test,construction methods,safety measures,quality control.The construction method of geotechnical pipe bag sand filling is analyzed and summarized,and the stacking preloading is studied in stages.The engineering practice shows that the stacking preloading effect is good in two stages,and the construction method of geotechnical pipe bag sand filling is practical,which is superior and significant in reducing the project cost and shortening the construction period,there by can provide reference for similar projects.
