中文摘要：

在这份报纸，基于多孔的媒介理论，全部的压力和输入的特定的表达式与两倍孔不饱和的广泛的土壤工作被建议，然后精力结合变量进一步被导出。我们在土壤行为上做在毛状的水和吸附的水的效果之间，以及在变丑之间的区别微 -- 并且宏观结构。根据为一个开的多相的热力学的系统的导出的输入工作表示和 work-energy-dissipation 关系，我们与两倍孔为不饱和的广泛的土壤建立一个基于热力学的建模框架。

英文摘要：

In this paper, based on the porous media theory, the specific expressions of the total stress and the input work of unsaturated expansive soils with double porosity are proposed, and then the energy-conjugate variables are further derived. We make distinctions between the effects of capillary water and adsorbed water on the soil behaviour, as well as between the deformations of microand macrostructure. According to the derived input work expression and the work-energy-dissipation relations for an open multiphase thermodynamic system, we establish a thermodynamics-based modelling framework for unsaturated expansive soils with double porosity.
