饱水岩石加载变形过程中视电阻率-渗透率的关联性

Analysis on the relation between resistivity and permeability of saturated rock during loading process

    摘要
  • 摘要: 根据岩石受载变形破坏过程中视电阻率和渗透率的演化规律,分析了岩体破坏过程中视电阻率和渗透率变化的关联性,指出饱水条件下岩石变形破坏过程中视电阻率与渗透率关系密切。基于Archie公式和Carman-Kozeny公式,推导出了饱水岩石渗透率和视电阻率之间的关系式。同时,从岩石加载过程变形破坏的细观分析角度,探讨了渗透率-视电阻率关系式的合理性,进而指出了其成立的基础条件和应用意义。

     

    Abstract: Aiming at the evolution of resistivity and permeability during loading process in rock failure, it is shown that there is a close relationship between resistivity and permeability under saturated state. The mathematical expression of resistivity and permeability based on equations of Archie and Carman-Kozeny was obtained. The micro-mechanism evolution of resistivity and permeability can be described as follows:the expanding and interaction of micro-cracks lead change. The application of the related model is also discussed.
