The invention discloses a tunnel water bursting disaster precursor information monitoring model test system and a test method thereof. The test system comprises a water-bearing body construction system, a triaxial pressurizing system and an excavation driving system, the triaxial pressurizing system applies a three-dimensional pressure to the water-bearing body construction system, and the excavation driving system is arranged in the working surface to be excavated of the water-bearing body construction system to quantitatively excavate the water-bearing body construction system; and the test data of the water-bearing body construction system is acquired by a data acquisition system and is analyzed by a data analysis system. Various disaster source water types are designed in the invention, and different water pressures and flows in the water-bearing construction enrich the form of a water bursting disaster source and enrich various water bursting types and water-rich forms. Water bursting precursor information in different forms of the water bursting disaster source is researched.
