The invention discloses a propelling speed prediction method and device for an earth pressure balance shield tunneling machine, a computer readable storage medium and an earth pressure balance shield tunneling machine. The method comprises the steps that: a speed prediction model is obtained by training an autoregression model structure with exogenous variables based on historical input and output data of a propulsion speed subsystem of the earth pressure balance shield tunneling machine in advance; the speed prediction model uses a multi-layer perceptron to fit nonlinear regression parameters of the autoregression model structure with the exogenous variables; propelling data information of the earth pressure balance shield tunneling machine before the current moment is obtained; the propelling data information is input into the speed prediction model; and the propelling speed of the earth pressure balance shield tunneling machine is determined according to an output result of the speed prediction model.
