[摘要]針對某機(jī)場場道的大面積軟基加固處理工程,采用了“高真空排水+強(qiáng)夯+沖擊碾壓”相結(jié)合的聯(lián)合處理軟基新技術(shù)。為研究高真空排水條件下采用大夯擊能強(qiáng)夯處理飽和軟土地基的可行性及用沖擊碾壓技術(shù)代替滿夯來壓實(shí)擠密土體表層的效果,對該聯(lián)合處理技術(shù)方案進(jìn)行了試驗(yàn)研究。試驗(yàn)結(jié)果表明,該技術(shù)處理效果好,施工速度快。試驗(yàn)為實(shí)際工程提供了合理的施工方法和施工工藝,進(jìn)而為展開大面積施工提供了保證。

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
