The
    permeability structure of rock mass controls the macro-permeability
    characteristics of fractured rock mass. However, the geological factors are
    complex and diverse. They control the permeability structure of rock mass. As
    to the actual engineering rock mass, the rock permeability structures are the
    hybrid types that are formed by basic permeable structure types. Through
    practical research at the field and statistical analysis, this paper summarizes
    five types of basic permeable structures that are widespread and four types of
    hybrid permeability structures and percolation characteristics in fractured
    rock mass. At last, it is concluded that based on hybrid permeability
    structures, the hybrid types of permeable structures are mainly Ⅲ-Ⅳ and Ⅰ-Ⅱ-Ⅲ. Also, the results are more in
    line with the actual situations.
