热力学是一种普适理论，因此非饱和砂土的变化过程必然也遵循热力学原理。利用热力学原理可以从更普遍的情况（条件）和更一般的视角审视非饱和土的水力－力学性质。本文基于热力学理论并考虑砂土的剪胀－各向异性以及塑性耗散之间的关系，建立固－液两相耦合的非饱和砂土本构模型的理论框架，更深入地揭示非饱和砂土复杂的行为和性质。

The mechanical behavior of unsaturated sands inevitably follows the principles of thermodynamics.By this method,we can study the hydraulic-mechanical behavior of soils with a general insight under a more universal law.Based on thermodynamical theory,and considering the relations among dilatancy,anisotropy and plastic dissipation of sands,a solid-liquid coupled constitutive modeling framework is established which can deeply indicate many complex behavior and properties for unsaturated sands.
