Abstract
The hydraulic causes of bridge failure have focused engineering attention on the bridge scour problem. However, in-situ bridge scour monitoring is still one of the rugged works for field application researchers. Especially for Taiwan, the island which is well known for its distinctive topography features that the central mountain range bisects the main territory from north to south leading to most rivers have short courses and rapid streams. This dissertation summarizes the development work that has been undertaken by the research team on in-situ bridge scour monitoring system in recently years. Fiber optical grating sensors, micro-electro-mechanical systems based pressure sensors and vibration-based detection sensors are applied to develop an innovative scour monitoring system for over water bridges. Several experimental results in the laboratory have proven the technologies developed could provide the scour-depth information near bridge foundation structures by using qualitative measurement deploy. Besides, practical experimental projects are also described in this study. The in-situ projects have brought up the preliminary implementation of installations of the system on field applications, which significantly contribute the useful feedback and the verification result to the development work of this research. Furthermore, the problems with challenge of running integrated projects are briefly mentioned. Though the actual performance of the scour monitoring system currently developed in this research needs time to be further verified and improved to meet the practical requirements for monitoring bridge scour under harsh environmental condition, this research indicates the importance of the bridge scour monitoring issues and propose a feasible way to do the further study for continued development work.
