In recent years, global warming leads rainfall intensity stronger than before. Therefore, bridge management requires a reliable monitoring platform in current, to monitoring of bridge piers based on the variations of safety and river erosion, can be timely warming of the bridge damage, and achieving the maintenance of bridges safety in the flood. In view of bridge design and construction technology, the bridge engineering technology has matured, however monitoring and maintenance are important factors in the safety of the bridge. And increased with time, no matter how good engineering, high safety factor and then the bridge has aged, the incidence of deterioration, plus traffic overload, the role of erosion and earthquakes, needs more strengthen its safety monitoring and maintenance to ensure safety.
