摘要
岩土介质的渗流过程实际上是流体对孔隙空间的占据过程，是一种几何意义上的相变。本文将岩土介质中的孔隙抽象为孔隙堆积体模型，用重正化群的方法研究了岩土介质的渗流问题，得出了临界孔隙率的定量计算方法，并根据有关数据初步验证了计算方法的正确性。
The process of seepage flow in rock and soil media,which is a process of fluid occupying the spatial pores in rock and soil,is a kind of geometrical phase transition.In order to idealize the pores in rock and soil,the pores packing model is introduced.By using the renormalization group method,seepage flow in rock and soil media is investigated and the calculation method of critical porosity is proposed.It is tentatively indicated that the predicated critical porosity is in good agreement with results from laboratory data.
