摘　　要：该文根据重庆苏家浩长江大桥拱箱缆索吊装方案的设计及应用,为了优化施工时拱箱吊装的扣挂方式,调整拱上建筑的施工顺序,通过先施工墩上排架,利用墩上排架满足拱箱的扣挂要求,完成拱箱吊装后再施工拱上建筑物。通过该文可为类似工程的缆索吊装设计及施工提供参考。Based on the design and application of cable-hoisting scheme for arch box of Sujiahao Yangtze River Bridge in Chongqing, the paper shows how to optimize the buckling of arch box hoisting in construction and adjust the above-bridge construction order by firstly constructing pier bents to meet the buckling requirements of arch boxes and then completing above-arch construction. It can offer some references for similar projects.
