Therefore, in view of the bridge collision-avoidance capability is weak and bridge lanes is narrow and deep. When the Three Gorges reservoir’s normal water, arch of the bridge will be partially submerged most of the time, and once the ship is out of control or off the course will collision arch and columns, which will cause arch bridge collapsed and serious safety accidents. This bridge’s resistance is weak along the direction of flow. The bridge is a reinforced concrete box arch bridge, which the arch and column are made of rectangular reinforced concrete thin-walled box structure.
Wanzhou Yangtze River Highway Bridge is in the perennial backwater area of the Three Gorges reservoir, which is a large arch bridge across the Yangtze River. Therefore, after the anti-collision facility construction of Wanzhou Yangtze River Highway Bridge, this paper does the research on the navigation condition of the reach and layout optimization measures, ensuring that the safety of the ship navigation test has been carried out on the ship model navigation in the bridge area. It is pointed out that the navigation conditions of Wanzhou Yangtze River Highway Bridge’s reach are complicated. The maneuverability similarity requirements of ship model with modified rudder (reduced rudder area by 28%) can basically be satisfied for navigation study.Ĭhen Mingdong studied on the navigation safety which is influenced by the construction of the bridge or some other building besides the river. In the document, scholars did the research on maneuverability calibration test of tow model for studying navigation of Three Gorges Project. The results are in good agreement with experiment data.

Xiong and Liu did the research on numerical prediction of propulsion factors of propelled ship model and full scale ship. The maximum rudder angle of the ship model test is generally set to 25 degrees, and 0.4 m/s is taken as the minimum speed. For the accurate description of the ship model navigation test, two kinds of different criteria are given in the document : rudder angle and minimum speed.
In order to study navigation problems of bridge area more visually and scientifically, navigation flow conditions and navigation conditions were researched by using ship model and physical model. The study of bridge area navigation problem can effectively protect the safety of the bridge and the ship.
