新吹填超软土工程特性研究进展综述

填海造陆的新吹填淤泥多呈流动的泥浆状态,含水率极高、孔隙比极大、强度极低,一般要搁置数年再进行加固。近年来,由于建设进度的加快,常需要边吹填边加固,在加固中遇到了诸多问题。对此,从沉积规律、固结试验、沉积固结理论等方面,综述了国内外新吹填超软土的研究进展,并提出研究中的不足,以便对新吹填超软土工程特性进行更深入的研究。

On Research Progress in Engineering Characteristics of Fresh Dredger Filled Super Soft Soil

The fresh dredger filled super soft soil in sea reclamation presents the state of flowing mud with high moisture content,extra-large porosity ratio and extra-low strength.It may be reinforced after being put out of use for several years in the past;however,due to accelerated construction speed,it needs to be hydraulically filled and reinforced at the same time in recent years and meets many troubles in the reinforcement.Therefore,from the sedimentary behavior,consolidation test,and settlement and consolidation theory,the research progress on the fresh dredger filled super soft soil at home and abroad with the defects therein were summarized so as to make further study on its engineering characteristics.
