THE RELATIONSHIP BETWEEN FRACTAL DIMENSION OF FISSURE NETWORK AND PERMEABILITY

摘要: 在前人裂隙网络水实验室试验的基础上,依据分形理论对裂隙网络复杂系统进行简单的统计分析,获得定量描述这一复杂体系的特征值——分维,并查明它与裂隙网络渗透率之间的关系。从计算结果可以看出,裂隙网络(指有效裂隙网络)的分维值与渗透率之间存在明显的正相关关系,这有可能为裂隙网络渗透率的定量评价提供一个简单而又实用的方法。

Abstract: Based on a previous laboratory test of fissure network water,a simple statistics and analysis is given by using fractal theory to obtain the characteristic value-fractal dimension,which can quantiateively describe this cimplicated fissure network system,and to find the relationship between the fractal dimension and permeability.The results show that there is a positive correlation between the fractal dimension and permeability.It may provide a simple and practical method to evaluate the permeability of fissure network.
