Problems solved by technology

The hydraulic coupling tests of rock mass at home and abroad are mostly carried out indoors on small-sized specimens. The specimens are specimens with random fracture networks or specimens with single fractures. When studying the hydraulic coupling problems of engineering rock mass, there are The following deficiencies: specimens containing random fracture networks cannot fully reflect the structural characteristics of complex fractured rock mass due to the small size of specimens; specimens containing single fractures cannot reflect the seepage field and stress field state of engineering rock mass
