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。
Aiming at the large-area soft ground reinforcement project of a certain airport’s airport, the new technology of soft foundation based on the combination of “high vacuum drainage + dynamic compaction + impact rolling” is adopted. In order to study the feasibility of using strong rammer to treat saturated soft ground under high vacuum drainage conditions and to replace the full ram with impact ram to compact the surface of compacted soil, the joint treatment scheme was studied Experimental Research. The test results show that the technology has good treatment effect and fast construction speed. The test provided a reasonable construction method and construction technology for the actual project, which in turn provided a guarantee for the commencement of large-scale construction.
