【摘要】：为更好地揭示东海大桥非通航孔所面临的船舶碰撞风险,采用空间有限元分析和截面能力计算对非通航孔桥墩的防碰撞能力进行计算,结果显示:东海大桥非通航孔桥墩只能抵抗小于500 t的驳船在漂移情况下速度不大于2 m/s的撞击,600 t的驳船以最低设计航速(2 m/s)的撞击能使桥梁结构失效,故桥梁结构难以抵抗600 t以上驳船的撞击。研究结果表明:东海大桥非通航孔船舶碰撞风险量化计算可以更加精确直观地表现东海大桥非通航孔的防船舶碰撞能力。
[Abstract]:In order to better reveal the ship collision risk of non-navigable holes in Donghai Bridge, the anti-collision capability of non-navigable orifice pier is calculated by using spatial finite element analysis and section capacity calculation. The results show that the non-navigable piers of Donghai Bridge can only resist the impact of barges of less than 500 tons with velocity of less than 2 m / s and less than 2 m / s under drift. The impact of barges with a minimum design speed of 2 m / s can make the bridge structure fail. Therefore, the bridge structure is difficult to resist the impact of more than 600 t barge. The results show that the quantitative calculation of ship collision risk with non-navigable holes in Donghai Bridge can more accurately and intuitively represent the anti-collision capability of non-navigable holes in Donghai Bridge.
