The Application of Dynamic Numerical Simulation to bridge navigation safety evaluation

According to the bridge site rational analysis and ship security control in the bridge area problem of bridge navigation safety evolution,using EFDC model to numerical simulation the 3-D flow fields of combined Highway and Railway Yangtze river bridge water area in Tongling,and using the simulation results as navigation simulation external environment fields for ship maneuvering simulation,the simulation results show that the bridge site is reasonable,but sweeping bend flow should pay attention to the impact of ship controlling.
