| 摘 要： | 土结构性模型是 2 1世纪土力学学科的核心问题。基于海积软土一维固结蠕变的宏观力学性状与微观结构定量分析相结合的方法 ,提出了软土在外荷作用下微观结构的演变模式 ,由此建议了一个含结构参数的固结变形本构关系。用试验资料和工程实例进行了初步验证 ,表明所建模型可以预测多级加载条件下海积软土的变形规律。

| Abstract: | Structured model of soil is a core problem in the 21th century on the research of soil mechanics. Based on analyzing mechanical behaviour and microstructure of marine soft soils under one dimensional consolidation-creep tests, a new mode of structure evolution under loading of marine soft soil is suggested. Therefore, a constitutive relation of consolidation of soft soil is constructed, in which several parameters are related to microstructure. The model was verified by data from laboratory testing and engineering practice. It is obvious that this model is useful to predict the consolidation deformation of marine soft soil under multi-loading condition. |
