摘要/Abstract

摘要： 围绕常溧线航道升级改造需要,研发了一种固定式复合材料防撞护舷,通过ANSYS/LS-DYNA有限元软件计算了防撞消能效果,采用真空导入工艺实现了工业化制造,通过钢管混凝土定位桩和膨胀螺栓实现了防撞护舷与桥墩之间的连接。结果表明,设置端头防撞护舷后,桥墩受到的最大横桥向船撞力下降38.0%;设置侧面防撞护舷后,桥墩沿横桥向、顺桥向方向受到的最大船撞力分别削减了41.8%、29.3%。复合材料防撞护舷性能优异,能大幅削减船撞力,有效保护桥梁结构安全,适应航道升级改造的需要,为内河航道桥梁的防撞保护提供了新的思路。

Abstract: Based on the upgrading of Changlixian channel, this paper developed one kind of fixed fiber reinforced polymer (FRP) fender. The ship collision force with and without FRP fender was calculated using ANSYS/LS-DYNA software. The FRP fender can be manufactured by vacuum assistant resin infusion process (VARIP) in the factory. With the combination of concrete filled steel tubular piles and the expansion bolts, the connection between FRP fender and bridge was solved. The results show that the maximum impact force can be decreased by 38.0% if the ship directly hits the head-on FRP fender instead of bridge in the transversal direction. With the side FRP fender, the maximum impact force can be reduced by 41.8% in the transversal direction and 29.3% in the longitudinal direction, respectively. Since it can greatly decrease the impact force, the FRP fender exhibits superior performance. It can meet the demands of upgrading the channel and effectively protect the bridge structure at the same time. Overall the FRP fender provides a new idea to design the anti-collision system for the inland waterway bridges.

Key words: fiber reinforced polymer (FRP) fender, numerical simulation, impact force, vacuum assistant resin infusion process (VARIP)
