The invention discloses a shield tunnel toughness monitoring method based on multi-source heterogeneous data, which comprises the following steps: multi-source heterogeneous data acquisition and computer data processing: in the multi-source heterogeneous data acquisition, tunnel displacement mu, tunnel section convergence D and tunnel disease area S data are respectively acquired; the computer data processing comprises the following steps: S1, data preprocessing; s2, data processing: processing the multi-source heterogeneous data preprocessed in the step S1, and calculating a tunnel performance index P and a tunnel toughness index Re; s3, tunnel state judgment; s4, artificial demonstration; s5, according to the state of the tunnel toughness in the step S4; s6, storing and archiving the processed data; and S7, terminal output: displaying and outputting the data obtained in the step S6 through multiple terminals. According to the invention, the tunnel can be comprehensively monitored, the monitoring result is r
