The invention relates to a bridge ship collision prevention collaborative early warning method and system based on digital twinning. The method comprises the steps that a physical entity in a target area is acquired, and a simulation model is built based on the physical entity by means of the digital twinning technology; calculating the ship collision risk degree of the bridge and the ultimate strength of the bridge member; estimating bridge ship collision time based on the simulation data corresponding to the bridge ship collision risk degree, calculating various types of water and land traffic evacuation time, and judging whether the bridge ship collision risk degree is an early warning threshold value or not based on the bridge ship collision time and the various types of water and land traffic evacuation time; and generating an early warning scheme based on the early warning threshold. The system is used for implementing the method. Compared with the prior art, the influence of secondary accidents caused by bridge ship collision events can be effectively prevented or relieved.
