摘　　要：结构健康监测是通过无损、实时的方式识别外部环境变化及结构自身变化,实现损伤识别、评估分析、安全预警等功能,从而快速辨别结构的健康状态的监测手段。结构健康监测系统可为项目的智慧管养、运维提供决策和支持,达到降低运营风险、延长结构使用寿命、节约运营成本的目的。文中从监测系统中监测内容的设计、监测平台的软硬件构建等方面对大连湾海底隧道结构健康监测系统进行介绍,应用反馈的监测数据验证了监测系统的准确有效性。Structural health monitoring is a monitoring method to quickly identify the health status of structures by identifying changes in the external environment and the structure itself in a non-destructive and real-time manner,realizing the functions of damage identification,assessment and analysis,and safety early warning.The structural health monitoring system can provide decision-making and support for the intelligent management,maintenance and operation of the project,so as to reduce the operation risk,prolong the service life of the structure and save the operation cost.This paper introduces the structural health monitoring system of Dalian Bay immersed tunnel from the aspects of the design of monitoring content in the monitoring system and the construction of software and hardware of the monitoring platform.The accuracy and effectiveness of the monitoring system are verified by the feedback monitoring data.

关 键 词：结构健康监测 沉管隧道 智慧管养 监测平台
