Damage Detection And Health Evaluate System Research About High Pile Pier In The Three Gorges Reservoir

After the Three Gorges Reservoir water hydrological conditions changed from the previous natural hydrology conditions into a reservoir hydrological conditions Moreover, with the improvement of hydrological conditions, navigation ability of upstream of the Three Gorges Dam has been greatly improved. And also with terminal use frequency increases, the increased load make the pier break, So the importance of the terminal detection on the rise, but the terminal detection assessment is slightly behind other industries. In this paper, we take the impact of high-pile wharf when Three Gorges Reservoir formed as the basis. According to high-pile wharf their environment, and structural characteristics. Research on Evaluation System health monitoring high pile pier in Three Gorges Reservoir. In this paper, research on the system is based on structural reliability theory. The AHP method in fuzzy mathematics used to get weight coefficient. Then introduced from the bridge inspection testing standards and scoring formula, in addition do some appropriate changes to them. So the wharf evaluation to have a more quantifiable indicators, instead of the previous one is completely qualitative detection conclusion. Then, based on quantitative, use the F method—emi gradient method—of fuzzy evaluation to let quantitative scores become a qualitative level description. Final formed of a workable, easy to understand detection system. So the evaluation result can make people have a qualitative and quantitative results to wharf health at the same time and more easy to understand the health level of whole pier. and easier to understand the overall health status of the pier. And are more likely to grasp overall health status of the pier. Have a big help to detect of high pile pier in Three Gorges Reservoir.
