摘要：
Shenyang Boguan Bridge is the first half-through 6-span X skew arch bridge in China. To ensure the safety during its construction and service, a complete set of structural health monitoring system is designed and installed on it. In this paper, the schemes of instrument selection and placement of measuring points, as well as the function, composition and realization of the monitoring system including the sensor subsystem, data acquisition and transmission subsystem, data management subsystem and condition assessment subsystem are introduced in detail. To satisfy the high-standard requirement of the quantity, distribution, measuring accuracy and synchronism, a set of distributed data synchronous acquisition instrument for structural health monitoring is self-developed, which realizes the accurate synchronous acquisition between multi-type sensors and multi-terminal instruments. This monitoring system has provided an effective means of real-time monitoring responses, on-line mastering the performance and reasonable planning the maintenance of the bridges. ©, 2015, Nanjing University of Aeronautics an Astronautics.
