通过对船撞力计算方法的研究成果进行比较归纳,将船撞力简化为锥形荷载,并将简化的船撞力施加在连续刚构桥全桥有限元模型上,得到了连续刚构全桥在船撞力作用下各关键截面位移、应力等参数的动态响应过程。结果表明,连续刚构桥在船撞力正面撞击作用下,全桥横向位移最大点位于中跨距离被撞桥墩一定距离处,碰撞过程中全桥应力最大值位于桩基与承台交接的位置。
Through the comparison of the research results of ship collision force calculation method, the ship collision force is reduced to the cone load, and the simplified ship collision force is applied to the full bridge finite element model of continuous rigid frame bridge. The dynamic response process of displacement, stress and other parameters of the bridge under the impact of the ship. The results show that the maximum displacement of continuous rigid frame bridge under the impact of frontal impact of the ship is located at a distance from the pier being struck by the midspan and the maximum stress of the full bridge is located at the place where the pile foundation and the cap meet .
