The invention discloses a method for predicting the pressure of a slurry cabin of a slurry shield based on multiple influence factors. The method comprises the following steps: step 1, acquiring data acquired by a PLC system of the slurry shield; step 2, carrying out muddy water bin pressure influence factor analysis, and obtaining influence factors; step 3, performing cleaning, feature extraction and sample division on the data according to the influence factors to obtain training set data and test set data; step 4, based on the training set data, optimizing a neural network topological structure by adopting a genetic algorithm in combination with K-fold cross validation, obtaining optimal network topological structure information and constructing an optimal model; step 5, training the optimal model based on the training set data to obtain a fitting model, evaluating the fitting model based on the test set data, and if the fitting model does not reach the standard, repeating the step 4 to the step 5 until the model prediction effect reaches the standard; and step 6, predicting the pressure of the muddy water bin at the next moment by using the standard model, analyzing whether a predicted value is in a proper range or not, and giving feedback information.
