Abstract
The bridge is essential in road system. It will affect traffic transportation and the road users significantly once it was damaged. The volume of traffic grows up rapidly, big cars increase, and serious overloading problems; Excess and illegal picking sandstone cause the riverbed descend, and the foundation is exposed seriously. Additionally, the potential threat of floods, mudflows and landslides will make the problems happen on the structure of bridge. To keep the function of bridge work well and the traffic transportation smoothly, regular examination of the bridge safety is necessary. And help us to understand the present state of bridge using, to adequately control the structure of building damaging, and judge the bridge damage scale by structure damage level. This research adopts C# programming language on .Net Framework to develop Windows software for the capacity of bridge prevent-flood which uses two different kinds of scouring depth: Melville and Coleman Method and CSU (Colorado State University) Method. Calculate the partial scouring effect to the pier when the flood scours, and then to understand the situation of foundation exposedness. According to the analysis of calculation, determine the safety of bridge, and maintain at the right moment.
The bridge management agency of government measures and fixes the bridge which the foundation seriously exposes constructively. Due to the limit of human resource and budget, it’s necessary to well-arranged using limited resource to make the highest efficiency of maintenance for bridge. Therefore this research use the analysis result from the capacity of bridge prevent-flood, then sort the repairing priority of bridge prevent-flood to understand the damage level of bridge clearly and help us to maintain and fix the bridge which the foundation exposes seriously.
