【摘要】：為更好地揭示東海大橋非通航孔所面臨的船舶碰撞風(fēng)險(xiǎn),采用空間有限元分析和截面能力計(jì)算對非通航孔橋墩的防碰撞能力進(jìn)行計(jì)算,結(jié)果顯示:東海大橋非通航孔橋墩只能抵抗小于500 t的駁船在漂移情況下速度不大于2 m/s的撞擊,600 t的駁船以最低設(shè)計(jì)航速(2 m/s)的撞擊能使橋梁結(jié)構(gòu)失效,故橋梁結(jié)構(gòu)難以抵抗600 t以上駁船的撞擊。研究結(jié)果表明:東海大橋非通航孔船舶碰撞風(fēng)險(xiǎn)量化計(jì)算可以更加精確直觀地表現(xiàn)東海大橋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.
