摘    要:通过在大面积堆载场地设置监测仪器,进行历时 3 a 的现场监测,对大面积堆载作用下软土地基的变形特性和加载条件、地层条件、排水条件、时间效应等的相关性进行分析研究,揭示了大面积堆载作用下软土地基变形特性不同于常规荷载作用下软土地基变形特性的规律,总结了在不同边界条件下软土地基变形和固结沉降的规律,为软土地基的固结沉降分析计算提供依据。

关 键 词:土力学  大面积堆载  监测  变形特性

Abstract:An in-situ monitor was installed on large-scale preloading field,where the field monitoring was preformed and lasted for three years. With the help of the date analysis of field monitoring,the paper presents the correlations among subsoil deformation, preloading construction,subsoil properties,permeability coefficient,and time period. It is found that deformation properties of soft subsoil under large-scale preloading are different from these under common loading,and the deformation and consolidation laws of soft subsoil with different border conditions during the period of preloading are obtained. The achieved results can provide a basis for the analysis and calculation of consolidation and settlement for soft subsoil.
Keywords:soil mechanics  large-scale preloading  monitoring  deformation property
