“…In this study, a X-ray CT imaging method was employed by leveraging these particular properties of KI solution to visualize the non-uniform flow formed during the percolation column test. As reported in an existing study, the concentration of the KI solution was 15 wt% ( Watanabe et al., 2019 ).

“…Fracture intensity was input on a per facies basis using a P 10 = number of fractures/length of scanlines = N/L*[L -1 ] ( Mauldon et al, 2000). P 10 measures abundance in a specified orientation, and so is converted into a direction independent P 32 , equivalent to fracture area per unit volume (P 32 =C 31 P 10 ; Mouldon et al, 2000;Wang et al, 2005). Consequently, the number of fractures measured in the field was dependent upon the orientation of the scanline, such that only fractures perpendicular to the scanline were sampled.…”

“…This phenomenon is particularly pronounced when tunneling activities intersect with deeply buried, weak rock layers rich in expansive clay minerals. The process of excavation in these scenarios triggers a rapid release of stored energy within the original rock matrix, yielding a dual effect: a redistribution of stress within the surrounding rock mass that leads to alterations in its state and the induction of a swelling effect [8][9][10][11] and the emergence of unloading surfaces that facilitate the development and extension of expansion strain.…”
