云川金沙江大桥防船撞装置与工程应用

Ship Anti-collision Device and Engineering Application of Jinshajiang River Bridge in Yunchuan

随着跨江桥梁的增多及航道的升级,越来越多的桥梁面临船撞风险。合适的防撞装置能增加桥梁的抗冲击能力,减小桥梁与船舶的事故损失。现介绍云川金沙江大桥的防撞装置,从消能效果验证、承载力验算等方面进行阐述,并列举工程应用实例,证明该装置的实用性。

With the increment of river-crossing bridge and the upgrade of fairway,more and more bridges are faced with the risk of ship col ision.The suitable ship impact device can increase the shock resistance of bridge and decrease the accident loss of bridge and ship.The article introduces the ship anti-col ision device of Jinshajiang River Bridge in Yunchuan,sets forth the verification of energy dissipation effect and checking of carrying capacity,takes an engineering application case and certifies the practicability of this device.
