【摘要】 针对桥梁通航安全评估中桥梁选址合理性分析和船舶在桥区水域的安全操纵问题,采用EFDC模型对拟建铜陵长江公铁两用大桥水域的三维流场进行了数值模拟,并将模拟结果作为航海仿真的外部环境场,用于船舶操纵模拟试验,模拟结果显示桥梁选址合理,但需注意扫弯水对船舶操纵的影响。更多还原

【Abstract】 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.更多还原
