| 摘要: |
| 对大跨径缆索承重桥梁进行合理的状态评估有助于掌握桥梁结构的技术状况、指导制定养护对策，以保证桥梁的正常运营和结构安全.首先综述了基于标准和规范的评估方法和基于系统工程理论的评估方法的研究现状及应用；其次对桥梁管理系统和长期监测系统的发展情况和评估数据信息源现状进行综述和分析；然后阐述了大跨径缆索承重桥梁状态评估面临的机遇和挑战，并提出了多源信息融合的功能模型和结构模型.综合分析表明：大跨径缆索承重桥梁评估规范的制定迫在眉睫；人工巡检信息和长期监测信息都有其各自的弊端，都难以独立成为桥梁状态评估的理想数据来源，引入多源信息融合技术，有望提高大跨径缆索承重桥梁评估结论的可信度；对缆索承重桥梁群实现评估方法标准化是未来发展方向之一.

| Abstract: |
| Reasonable condition evaluation for large span cable supported bridges could reveal the actual condition of the bridges, make rational maintenance and repair strategy, and ensure the operational and structural safety. Firstly, the evaluation methods were reviewed based on the standards, specifications and system engineering, respectively. Secondly, the development of bridge management system and long monitoring system, and the status of evaluation information sources were analyzed and discussed. Finally, the chances and challenges were proposed faced by large span cable supported bridge condition evaluation, and the multi-source information fusion functional and structural models were presented. Reviews analysis shows that the evaluation standard for large span cable supported bridges is imminent. Visual inspection and long term monitoring, due to their disadvantages, cannot support bridge condition evaluation respectively. Information fusion induced to bridge condition evaluation is expected to increase the credibility of bridge condition evaluation results. Standardized evaluation method for cable supported bridge group is one of future development directions.
