Visual test system and method considering rock fracture biological reinforcement-seepage-temperature coupling effect

The invention discloses a visual test system and method considering a rock fracture biological reinforcement-seepage-temperature coupling effect. The system comprises a slurry storage assembly, a dynamic monitoring assembly, a detachable seepage assembly, a temperature regulation and control assembly and a visual assembly. According to the method, the MICP grout is adopted to sequentially pass through the grouting pump and the grouting pipeline, and rock mass gaps are reinforced through MICP grouting; and meanwhile, excessive MICP grouting liquid can flow back to the MICP storage container to be recycled. In addition, the MICP slurry is small in viscosity, the reinforcing diffusion range is wider under low pressure, and the reinforcing effect on rock mass cracks is better. According to the invention, visual observation of rock mass seepage at different temperatures can be considered after microorganisms reinforce rock mass gaps, the seepage process of the rock mass structural surface can be observed truly and
