Autor: Xue Dongjie, Hou Mengdong, Cheng Jianchao, Jia Zhen, Liu Yintong, Xin Cui, Xu Yanzhuo, Wang Lujun

Publikováno v: 矿业科学学报, Vol 8, Iss 5, Pp 663-676 (2023)

The Beishan area in Gansu province is the main pre-selected site for deep geological disposal of high-level radioactive waste, it therefore bears implications for the study of fracture seepage characteristics of granite caused by shear failure. This

Autor: Li Yingjie, Wang Bingqian, Zuo Jianping, Xue Dongjie, Liu Dejun

Publikováno v: 矿业科学学报, Vol 7, Iss 4, Pp 481-489 (2022)

Based on the fracture mechanics theory of the isotropic Hoek-Brown strength criterion, this paper established the initiation conditions of the bifurcated microcrack along bedding which begins with the meso-fracture mechanism of laminated rocks. Then

On the theoretical calculation of tortuosity in porous media and its experimental validation

Autor: Xue Dongjie, Zhao Aibo, Liu Kuichang, Hou Mengdong, Fu Yanyan, Xin Cui, Xu Yanzhuo

Publikováno v: 矿业科学学报, Vol 6, Iss 5, Pp 615-622 (2021)

The quantitative characterization of connectivity of pore geometry and its reconstruction of topological connectivity are two important methods to describe the laws of fluid seepage in porous media.However, the lag of theoretical work severely restri
