## Consolidation Theory of Unsaturated Soil Based on the Theory of Mixture(Ⅰ)

• 摘要: 非饱和土是由土粒、水、气组成的三相介质,本文以混合物理论为基础研究了非饱和土的固结问题.文中导出了各向异性多孔介质及非饱和土的有效应力的理论公式,把有效应力原理和Curie对称原理作为非饱和土的两个重要的本构原理,建立了非饱和土固结的数学模型:由25个方程求解25个未知量.在增量线性化的情况下,本模型简化为5个控制方程求解5个未知量:3个固相位移、孔隙水压力和孔隙气压力.模型中包含7个材料参数,都可由试验测定,便于工程应用.Biot理论是本模型的特例.
