超深淤泥质地层单轴水泥土搅拌桩技术

Technology of Single-axis Cement-soil Mixing Pile in Ultra-deep Mucky Stratum

浙大超重力项目为国家重点项目,地质复杂,地层上部淤泥地质地层约12~15 m厚,呈灰色、饱和、流塑状态,地基需采用单轴搅拌桩进行加固处理,施工前对行搅拌桩工艺参数进行试验,并对相关的数据及处理效果进行研究,为下一步施工提供可靠的保证。

The super-gravity project of Zhejiang University is a national key project with complicated geology.The silt geological stratum in the upper part of the stratum is about 12~15 m thick and is in the state of gray,saturated and flowing plastic.The foundation should be reinforced by single-axis stirring pile,in order to provide a reliable guarantee for the next step of construction,the technical parameters of the row mixing pile are tested before construction,and the related data and treatment effect are studied.
