［摘要］针对某机场场道的大面积软基加固处理工程，采用了“高真空排水+强夯+冲击碾压”相结合的联合处理软基新技术。为研究高真空排水条件下采用大夯击能强夯处理饱和软土地基的可行性及用冲击碾压技术代替满夯来压实挤密土体表层的效果，对该联合处理技术方案进行了试验研究。试验结果表明，该技术处理效果好，施工速度快。试验为实际工程提供了合理的施工方法和施工工艺，进而为展开大面积施工提供了保证。

Abstract:Aiming at the improving large-area soft ground of an airforce airport, a new technology is taken into practice, which combines the high vacuum drainage, dynamic compaction and impact compaction technology. In order to research the feasibility of treating the saturated soft ground with large dynamic energy in the condition of high vacuum drainage and the effect of impacting shallow soil using impact compaction technology instead of full compaction, the experimental research is carried out to test the combination technology. The experiment indicates that this combination technology can handle soft ground quickly and effectively, and it produces the reasonable construction method and technique, so it can ensure the large-area construction of this engineering.
Keywords:airport engineering; soft ground treatment; high vacuum drainage; dynamic compaction; impact compaction; test
