The invention provides a prediction model establishment method, prediction method and device for tunneling speed, and the method comprises the steps of obtaining the attribute parameters of different surrounding rocks, and carrying out the clustering processing of the attribute parameters of a plurality of surrounding rocks, and obtaining a plurality of clustering results; establishing an empirical formula based on the plurality of clustering results, and training the empirical formula based on the attribute parameters of the surrounding rock to obtain a regression formula; and processing the regression formula to obtain a standard linear regression model. By means of the invention, on the premise that normal tunnel construction is guaranteed, the tunneling speed of the TBM can be predicted through the artificial intelligence technology, the tunneling speed better fitting the actual construction geological condition is obtained, then normal tunneling of the TBM is effectively guided, and the construction peri
