Three-dimensional physical simulation test system for water inrush and mud inrush of deep roadways and tunnels

The utility model discloses a three-dimensional physical simulation test system for water inrush and mud inrush of a deep roadway and a tunnel. The three-dimensional physical simulation test system comprises a test bed, a ground stress loading system, a water pressure loading system, a data acquisition system and a muddy water outburst recovery system, a test box body used for being filled with media such as surrounding rock media and faults is arranged in the test bench, the ground stress loading system is located at the top of the test box body, and the water outlet end of the water pressureloading system composed of a constant-temperature constant-pressure water tank, a high-pressure nitrogen cylinder and the like is arranged in a gravel filter layer of a water inrush structure such asthe faults. The data acquisition system is composed of a plurality of sensors arranged inside the surrounding rock or the fault medium and a test bed external data acquisition instrument. The muddy water protrusion recovery s
