二维裂隙渗流等效渗透系数张量的一种近似算法

AN APPROXIMATE METHOD FOR CALCULATING THE EQUIVALENT PERMEABILITY TENSOR OF SEEPAGE IN COMPLICATED FRACTURES

  • 摘要: 地质体裂隙渗流十分复杂,通常可用等效渗透系数张量来描述其渗透特性. 本文基于无限延伸的多组平行裂隙的等效渗透系数张量的叠加算法,通过引入裂隙的贯通系数概念,并结合随机裂隙网络生成技术,发展了一种可用于估算二维裂隙等效渗透系数张量的叠加算法.

     

    Abstract: Seepage through fractures in a geologic body is a very complex issue. Usually, its macro-seepage characteristics can be described by the equivalent permeability tensor. Based on the superposition algorithm for calculating the equivalent permeability tensor for multiple sets of infinity parallel fractures, this paper proposes a kind of more general superposition algorithm by introducing the concept of the through coefficient of fracture. Combining with the computer-generated technology of the random fracture network, the method can be used to approximately estimate the equivalent permeability tensor of two-dimensional random fractures.
