After the free energy and the specific free energy are re-defined in theory, the elastic-plastic constitutive model of gypsum breccia considering expansion and damage are built.
在理论方面，通过对自由能、比自由能的重新定义，建立了考虑膨胀影响的膏溶角砾岩弹塑性本构模型。

To sum up, the swelling characteristics and the mechanical properties of gypsum breccia are detailedly studied through experiments. The swelling models and the water damage model are established.
本文在试验方面详细研究了膏溶角砾岩的膨胀和力学特性，建立了膏溶角砾岩的膨胀模型和水损伤模型；
