The complex site conditions of Lingdingyang Bridge on Shenzhen-Zhongshan Link lead to many construction difficulties. The design of the support affects the construction quality of the super-height, large-weight and long-span beam on the cable tower. In order to achieve a high-standard construction and control the quality of the project, three support design schemes for the upper beam of the east cable tower of Lingdingyang Bridge were studied and compared by calculating and analyzing with the finite element software. Ultimately, the plan of the upper arch bracket stands out among the three schemes. The bracket scheme can not only meet the quality requirement of the main structure, but also reduce the construction difficulty and cost of the temporary structure, which can provide reference for the design of similar projects in the future.
Key words: Shenzhen-Zhongshan Link / cable tower / upper beam support / comparisons.
