摘要
提出了大跨径钢筋混凝土拱桥船桥碰撞的计算方法,采用3 000 t内河船舶撞击力时程对拱桥主拱圈进行纵向撞击和横向撞击模拟,得出主拱圈的动力响应特性.计算结果表明其位移值都不大,主拱圈大部分始终处于受压状态,处于弹性工作范围.
The method of calculating the ship collision to RC （ reinforced concrete） bridge is proposed in this paper. The 3 000 t time-history force of ship collision in the inland river is adopted to simulate the along and cross direction impact. The dynamic responses of main arch ring are concluded ： the displacement is not obvious; most of the main arch ring is in compression; and the compression stress is in the extent of elastic work.
