摘要:: 目前,平地真空预压、堆载预压、真空联合堆载预压施工技术已广泛应用,但对于深基坑真空联合高堆载施工技术需要进一步研究和探讨。在南水北调东线第一期工程里下河水源调整工程阜宁站工程施工中,通过科技研发和攻关,采用了深基坑真空联合高堆载预压处理软土地基技术,在工艺上不断创新突破,解决了深基坑软土地基处理难题,取得了显著的效果,为软土地基工程施工提供了新的可行的施工技术应用。

Abstract:: At present, the construction technology of flat ground vacuum preloading, heaped load preloading and vacuum combined with heaped load preloading has been widely used. However, the deep foundation pit combined with high heaped load preloading needs further research and discussion. In the construction of Funing station of Lixiahe water source adjustment project of the first phase of the east line of South to North Water Transfer Project, through scientific research and development and tackling key problems, the deep foundation pit vacuum combined with high heaped load preloading was adopted. The soft soil foundation technology had been innovated and broken through continuously in technology, which overcame various technical difficulties, successfully solved the problem of soft soil foundation treatment of deep foundation pit, and achieved remarkable results, providing a new and feasible construction technology application for soft soil foundation engineering construction.
