Abstract: Based on the infrastructure project in Oujiangkou new district of Wenzhou city, this paper studies the consolidation deformation law of marine muddy clay during vacuum preloading. Combined with the common settlement prediction methods, the prediction of foundation settlement after construction is carried out. The applicability of each settlement prediction methods is also analyzed, for reference.

Key words: vacuum preloading, soft soil foundation, consolidation deformation, settlement prediction

摘要： 依托于温州市瓯江口新区基础设施工程，研究瓯江口地区海相淤泥质黏土在真空预压处理加固期间的地基固结变形规律。结合常用的沉降预测方法对瓯江口地区地基工后沉降进行预测分析，探究不同沉降预测方法对瓯江口地区软基处理的适用性，为类似工程提供参考。
