摘要
土结构性对工程特性具有重要影响。通过内、外因对宁波软土结构性的成因进行分析以及单向固结试验和常规三轴固结不排水试验,对比宁波地区典型淤泥质软土原状土与重塑土的试验结果,系统对其结构性引起的压缩特性、孔压特性以及强度特性进行研究,以分析结构性对宁波软土工程特性的影响。最后根据试验成果提出在该地区软土本构模型研究中应注意考虑的问题。
Soil structure has significant influence on its engineering properties, the formation of soft soil structure in Ningbo area is analyzed from the internal cause and external cause. To analyze the soil structural effects, by means of onedimensional consolidation test and consolidated undrained triaxial test, differences of compression properties, properties of pore water pressure, and strength properties which are caused' by structural property are systematic analyzed by contrast with the test data of undisturbed sample with remolded sample of typical mucky soft soil in Ningbo area. Finally problems which should be considered in constitutive model for Ningbo clay on the basis of experiment results are presented.
