New-builtbridges andold bridges in inland waterwaysnear layout,the intersects angle that the normal direction of bridges axes andthe flow directionis more than 5, it is an important issuethat the navigable effective widthis determinedscientificallyand reasonably to ensure the safety of ships and bridge.In this paper, navigable effective clearance widthof two bridges as a wholeare calculated based on channel conditions and pier layout,which calculate the navigable effective width in the channel direction by oblique projection, determine the turbulence width by physical model test, graphicsand compare. Finally, taking the Lijiatuo Yangtze River secondbridge project in Chongqing as an example, the scientific and rationality of this method is verified, which can provide reference for the determination of navigable effective clearance widthof similar bridges in the future.
