文章在考虑颗粒可压缩、孔隙流体的密度是温度和压力函数的情况,采用两相流不混溶流体的理论推导了在多孔介质中温度-两相渗流-变形的耦合模型,使用Galerkin方法将各控制方程在空间域和实践域进行离散,初步开发了相应的有限元程序。两个算例的数值模拟结果表明耦合模型可以比较准确地反映非饱和土在温度和压力变化时饱和度和沉降变形的规律,也验证了程序的准确性。 In this paper, considering the compressibility of particles and the density of pore fluid as a function of temperature and pressure, the coupled model of temperature-two-phase seepage-deformation in porous media is derived using the theory of two-phase immiscible fluid. The Galerkin method The control equations are discretized in the spatial domain and the practice domain, and the corresponding finite element program is initially developed. The numerical results of the two numerical examples show that the coupled model can accurately reflect the saturation and settlement deformation of unsaturated soils under temperature and pressure changes, and also verify the accuracy of the program.
