| Summary: | 博士 === 中原大學 === 土木工程研究所 === 104 === Currently, establishment of the system used in the real-time monitoring on the pier. When the huge amount data, can not meet all of the data stored. It may be measured once in 30 seconds, and so on for processing. However, full-time data is of great value, contains important messages such as floods, earthquakes, etc. How to establish a true 24-hour real-time monitoring system for the pier is a subject.
In this study, the target for scour type piers of the highway bridge. Through 24-hour monitoring of permanent inclination displacement pier instantaneous vibration displacement characterization phenomenon. Through the planning and design the monitoring system. Establish a real-time and stable, and capable of reaction piers real status of the static and dynamic displacement system, and to assess its effectiveness.
In Taichung Dongshi Bridge for the subject, after site survey and data collection for the main(P7) and secondary watercourse (P3) piers as the goal. Through equipment selection, system settings, error analysis, and because of the huge amount dynamic monitoring data, the planning and design of the rear end of the dynamic signal processing software for real time processing of large data. Through the planning of static and dynamic data storage management, let each data will not be lost and the effective use of database storage space. Through previous bridge stability and security analysis to manage static and dynamic real-time monitoring of displacement. The stored of vibration acceleration data can be immediately retrieve after the earthquake, and proceed with Hilbert-Huang Transform analysis to assess the current status of the piers. The eventual establishment of bridge closure mechanism processes to provide real-time messages to the bridge''s management, and following dangerous situations.
