This invention relates to the field of facility durability assessment technology, and in particular to a life-cycle durability assessment
system for cross-sea bridges in highly corrosive coastal environments. The
system includes: a multi-source heterogeneous
data acquisition module, used to acquire corrosive environment data, structural response data, component apparent damage data, and historical material performance data through a sensor network,
image acquisition equipment, and
database deployed on the bridge body and its environment; a data fusion and spatiotemporal registration module, connected to the multi-source heterogeneous
data acquisition module, used to clean, align, and standardize the acquired heterogeneous data, and establish a mapping relationship between
environmental exposure, material damage, and structural response; and a full-link intelligent
system encompassing data
perception, fusion analysis, AI prediction, dynamic calibration, and assessment decision-making. Through the fusion of physical mechanisms and data-driven approaches, this system achieves a fundamental shift in cross-sea bridge durability assessment from experience-based judgment to accurate prediction, and from passive maintenance to proactive operation and maintenance.
