The invention discloses a damping-adjustable suspension control method and device for a multi-axle special vehicle, and relates to the field of vehicle design control. The method comprises the following steps: acquiring operation information of the multi-axle special vehicle; determining reference dynamic state information based on a whole vehicle ceiling damping reference model; determining a sliding mode control quantity according to the actual dynamic state information and the reference dynamic state information; according to the sliding mode control quantity and the damping force grouping distribution strategy, the expected damping force of each suspension is determined; for any suspension, the expected damping force and the suspension compression amount signal are input into the hydro-pneumatic suspension damping force neural network model, and a control signal is obtained; the control signal is used for adjusting the damping force of the suspension of the multi-axle special vehicle in the running process; the driving smoothness and the control stability of the multi-axle vehicle can be improved.
