Title:
BRIDGE MULTI-SOURCE, MULTI-SCALE INTELLIGENT HIERARCHY EARLY WARNING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/016415
Kind Code:
A1
Abstract:
A bridge multi-source, multi-scale intelligent hierarchy early warning method and system, the method comprising: establishing a bridge finite element model and a mid-span model having maximum bridge deflection; on the basis of the constructed model, analyzing the impacts of various influencing factors on down-warping of a bridge and obtaining the internal force experienced by the bridge under different down-warping degrees, thereby analyzing corresponding bridge crack conditions, while also determining a mid-span deflection threshold of the bridge; on the basis of the bridge crack conditions, dividing the mid-span deflection threshold of the bridge, so as to obtain risk assessment levels; establishing corresponding relationships between various influencing factors and changes in deflection and cracks, and determining actual deflection and crack conditions of the bridge according to actual values of various influencing factors, thereby determining a corresponding risk assessment level. The described bridge multi-source, multi-scale intelligent hierarchy early warning method can achieve hierarchical early warning of the deflection and cracks of a continuous rigid-frame bridge; corresponding countermeasures are selected according to the grades of the deflection and cracks of the continuous rigid-frame bridge, so as to guarantee the safety and durability of the bridge structure during service.
