嘉兴至绍兴跨江公路通道项目嘉绍大桥横跨钱塘江尖山河段,潮强流急,航运条件复杂,桥梁船撞风险巨大。为控制强涌潮急流水域船舶撞击桥梁的风险,通过研究,主航道桥及北副航道桥采用固定式防撞套箱进行被动防撞,单桩独柱引桥通过保留钢护筒的措施提高桥墩的防撞安全性能。此外全桥还建立了防船撞主动预警系统,包括AIS监管系统、VHF通信系统、桥区主动预警视频监控及报警系统、电子海图显示与信息综合系统。
Jiaxing-Shaoxing Cross-River Highway Project The Jiashao Bridge crosses the Jianshan River section of Qiantang River. The tidal current flows rapidly and the shipping conditions are complex. The risk of bridge collision is huge. In order to control the risk of a collision of a ship with a strong surge and a sharp water jet, a passive anti-collision was conducted by using a fixed collision avoidance box on the main channel bridge and the north auxiliary channel bridge. Crash safety performance. In addition, the whole bridge also set up an anti-collision initiative warning system, including AIS regulatory system, VHF communication system, bridge area active early warning video surveillance and alarm system, electronic chart display and information integrated system.
