| 摘 要： | 长江河口滨海地区广泛分布有大量的冲填土,由于其形成时间短,具有欠固结特性,因此对地面沉降影响较大。本文首先阐述上海市临港新城区冲填土分布特征,并按其填料不同将其分类后计算出不同种类冲填土大面积堆载所引起下部土层的地面沉降量和冲填土本身固结产生的沉降量,并与总的地面沉降量相比较,得出结论,并对进一步开展工作提出建议。

| Abstract: | There are vast non-consolidated alluvia deposits freshly formed in estuary area of Yangtze River and nearby coastal area.The deposits contribute to land subsidence.Based on their distribution,two subsidence volumes of different kinds of deposits are respectively calculated due to their consolidation and underlayer soil consolidation.It is found that the subsidence induced by the deposits has a larger ratio of the total surface subsidence.And also the suggestions for the in-depth study on deposits are discussed in this paper. |
