以舟山大陆连岛工程为背景，阐述和讨论了在跨海大桥中开展健康监测的重要性和研究现状，并分析了跨海大桥健康监测和损伤识别所面临的关键技术问题和研究趋势，提出了考虑非线性效应和荷载激励特征来开展复杂结构损伤识别的研究思路，以提升通过大型健康监测系统来实现桥梁损伤评估的能力。

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.
