摘要
华东沿海地区淤泥具有压缩性高、含水量高、承载力低、呈明显的流塑软塑状特点,基坑开挖风险极大,本文通过对某长大基坑全面详实的监测,并结合施工工况进行分析,总结出深厚淤泥地层深基坑开挖变形的规律与原因,提出针对性的开挖方法及施工对策,对类似软土深基坑的开挖具有一定的借鉴意义。
The silt of the East China Sea has the characteristics of high compressibility,high water content,low bearing capacity,and obvious flow plastic soft plastic. Excavation great risk,the article brought up by a comprehensive and detailed monitoring of excavation and construction conditions combined with the analysis,summed up the deep silt layers deep foundation pit excavation deformation rules and reasons are proposed for the excavation method and construction countermeasures,of similar soft soil deep foundation pit excavation has certain reference significance.
