摘　　要：介绍汉江某大桥施工的主要过程,讨论其中所采用的关键技术措施,包括施工过程中标高与应力修正、施工方案调整等。实践证明,在这座大桥施工过程中所采用的技术措施具有很强的实用性,不仅对大桥的成功修建起到关键的作用,也为同类型大跨度连续梁桥施工控制提供参考。This paper describes the principal process of the construction for some bridge over the Hanjiang river and focuses on the discussions of the critical techniques used in the control, like elevation and stress force revising for erection and construction plan adjusting. It is shown that the critical techniques adopted in the construction control of the bridge are very practical. They not only play a crucial role in the successful erection of this bridge, but also provide reference for similar long-span continuous-rigid bridges construetion.
