摘　　要：川藏界白格堰塞湖第二次泄洪冲毁国道318线金沙江大桥,为尽早恢复国道通行,提出了架设简支战备钢桥的抢通保通方案。通过恢复重建桥位、桥型比选,确定了原位重建连续刚构桥建设方案,分析了重建桥梁防洪能力、设计计算成果及刚构桥的施工方案,可供同地区类似工程参考。The second flood discharge of the Baige barrier lake in the Sichuan-Tibet boundary destroyed the Jinsha River Bridge on National Highway 318.In order to restore the passage of the national highway as soon as possible,a plan for the construction of a simple-supported war-ready steel bridge was proposed.Through the restoration and reconstruction of bridge location and bridge type comparison and selection,the in-situ reconstruction of continuous rigid-frame bridge construction plan was determined,and the flood control capacity of the reconstructed bridge,the design calculation results and the construction plan of rigid-frame bridge were analyzed,which can be used as a reference for similar projects in the same area.
