The invention relates to a bridge structure
toughness state regulation and early warning method and
system, and solves the problems of splitting and response passive
lag of each link in bridge operation and maintenance, and the method comprises the steps: collecting the internal
sensing data of the bridge structure state and material performance, synchronously obtaining the external multi-dimensional data of weather, traffic and geology, and carrying out the early warning of the bridge structure
toughness state. A global sensing dynamic
information field is generated through fusion
processing; based on the
information field, driving the digital twin to carry out multi-scene
coupling deduction, and when a response exceeds a threshold value, deciding and outputting a graded early warning
signal and a corresponding pre-intervention strategy according to a
toughness evaluation system; according to the early warning
signal and the strategy, if an automatic execution condition is satisfied, a control instruction is issued to the distributed network to execute active adjustment; otherwise, generating a digital plan and pushing the plan to a specified terminal. The method has the following effects that fundamental transformation of bridge operation and maintenance from passive
lag to active look-ahead is achieved, and the self-
adaptive capacity and the overall toughness of the
system are remarkably enhanced through intelligent closed-loop linkage.
