【摘要】 苏通长江大桥主桥是目前世界上在建的跨度最大，跨径为1088m双塔双索面斜拉桥。由于在斜拉桥施工控制技术的实践经验和研究成果上，国内外主要集中在中、大跨度的斜拉桥，对于此类千米级特大跨度斜拉桥的相关实践经验还比较少。以往，国内斜拉桥施工控制均采用传统的施工控制方法，还未进行过采用几何控制法进行施工控制的实践经验和相关研究探索。为了进一步推动斜拉桥施工控制理论与实践的发展，本文以苏通长江大桥主桥为工程背景，介绍研究了几何控制法的基本理论，以及其在苏通长江大桥主桥施工控制中的具体应用。文中还对苏通长江大桥双悬臂施工中应用几何控制法的结果进行了评估，并讨论得出了几何控制法在斜拉桥施工控制进一步广泛应用的一些有意建议。更多还原

【Abstract】 Abstract: The main bridge of Sutong Yangtze Bridge under construction is a cable-stayed bridge of double pylons and cable planes with main span of 1088m, which will be the longest span cable-stayed bridge in the world after completion. Since most construction control experience regarding cable-stayed bridge mainly focused on comparatively medium span bridges before, there is little experience and research on construction control of extra-long span cable-stayed bridge for reference. In China, most popular construction control methodology for cable-stayed bridges is emphasized on structural internal force during erection, while geometric control research has never been performed. In order to promote the theoretical and implementary development of construction control methodology for long span cable-stayed bridges, this dissertation introduces the principle of geometric control methodology and detailed application in construction of Sutong Bridge. It also makes assessment on the geometric control results derived from cantilever construction of Sutong Bridge and presents some constructive suggestions for further application of geometric control methodology in erection of cable-stayed bridges.更多还原
