摘要/Abstract

摘要： 自然灾害、超载运营、长期服役导致的材料劣化和结构性能退化等多因素耦合影响下，大型桥梁运营安全问题日益突出。利用现代信息传感技术进行桥梁安全监测与评估技术的研究，已成为桥梁研究课题的热点。通过对桥梁海量监测数据的分析，提出了基于结构响应包络、时变可靠性和劣化效应的桥梁安全评估技术；针对桥梁长寿命和传感器短寿命的不匹配问题，提出了基于预埋-表贴传感器“接力”的监测模式，构建了桥梁从建设期到营运期的全寿命安全监测技术体系；自主研制了实用性强的系列桥梁监测装置。提出的大型桥梁安全监测评估技术与装置已应用于诸多工程实践，验证了其有效性与实用性。

关键词: 桥梁安全, 监测, 评估, 技术与装置

Abstract: Influenced by such diversified coupling factors as natural disaster, overload and the natural deterioration of materials and structure owing to long-term service, the safety of large bridges in operation has become increasingly obvious. Research on bridge safety monitoring and evaluation technology based on modern information sensing technology has been much discussed in bridge research. Based on the massive monitoring data of bridge, the bridge safety assessment techniques based on the structural response envelope, time dependent reliability and deterioration effect have been proposed. To solve the misalignment between the long-life bridge and short-life sensors, the monitoring mode of “relay” has been put forth, and the life-long safety monitoring system of the bridge from construction period to the operation period has been established. A series of bridge monitoring devices with strong practicability have also been developed independently. Technologies and devices for the safety monitoring and evaluation of large bridges have been much applied to practice, and their effectiveness and practicality verified.

Key words: bridge safety, monitoring, evaluation, technology and device
