Abstract
Taking Zhoushan Mainland-Islands Link Project as an example, the importance and research status quo of health monitoring study of trans-oceanic bridges were discussed. Then, the key techniques and study direction were analyzed, and the study idea of structural damage identification considering nonlinear effect and load feature were presented to improve bridge damage evaluation ability by a comprehensive health monitoring system.
Keywords
