摘　　要：随着渗流力学在各个领域的发展,很多问题需求描述细观的渗流过程例如多孔介质中气液界面的运动。本文基于多孔介质,阐述了经典渗流力学、CT扫描建模技术、逾渗理论、微观渗流仿真模拟技术和拓扑网络模型等若干方法对细观单相渗流与多相渗流的描述与解决方法,并对每种方法的特点进行总结分析,展望了发展前景。With the development of seepage mechanics in various fields, many problems demand the flow process of micro seepage such as the movement of gas-liquid interface in porous medium. In this paper, the problems and solutions of the single phase and multi phase micro seepage based on the classical seepage mechanics, CT scanning technique, percolation theory, micro seepage simulation technique and topology network model in porous medium are expounded. Also the characteristics of each method were analyzed, and the future development was prospected.
