摘要
应用两相渗流原理分析了非水溶性浆液在饱和岩土介质中的渗流特点。引入相对渗透率概念，建立了能反映浆液灌入动态过程及饱和度变化的非稳定渗流力学模型及浆液自动吸渗过程的微分方程。通过试验对理论计算进行了检验。
The permeation characteristics of immiscible grout in saturated media is analysed based on the two-phase fluid flow theory. The concept of relative permeability is introduced. The dynamic permeation models are well established, which can represent imbibition and be used to predict the distributions of grout saturation. Experiments are conducted to verify the validity of the models.
