本文从两相流体动力学的守恒方程出发，考虑固相、液相的相对运动，推导了可以考虑场的不均匀性和流体压缩性的统一形式的控制方程，并对方程所基于的物理概念和相互联系进行了必要的分析。通过对方程适当形式的表达，可导出用于大、小变形固结、渗流和沉积的简化方程，显示了在不同领域的三个理论存在一定的统一性。方程推导过程并未对本构关系加以限制，适用范围较广。依据实际问题的要求，作了不同形式的简化。
Based on the conservation equations of two-phase fluid dynamics, a uniform governing equation that accounts for field inhomogeneities and fluid compressibility is derived by considering the relative motion of the solid and liquid phases. The physical concepts on which the equations are based And the necessary analysis of the interconnected. The simplified equations for large and small deformation consolidation, seepage and sedimentation can be deduced from the proper expressions of the equations, showing that there is some unity among the three theories in different fields. The process of derivation of equations does not limit the constitutive relations and has a wide range of applications. Based on the actual requirements of the problem, made different forms of simplification.
