After construction of bridge over curved river, due to large angle between flow to the normal of bridge′s axis,high flow speed and not wide enough clear span of bridge, ships may hit the bridge pier when passing the bridge. At the same time, the evolution of the bed of curved river can produce unfavorable influence on navigation. So, it is of great significance to study the navigation-obstructing problem of this kind of bridge. Combining the engineering practice, this paper studies the reasons of navigation obstruction at bridge section of curved river and puts forward regulation measures, which may serve as a reference for similar projects.
