【Abstract】 Fuzhou Xiuzhai Tollgate located on Fuxia Expressway consists of two parts. One is a concrete leaning tower which is 44 68 meters high with a sloping angle of 68 degrees. The other is a structure of circular arch steel-tube truss stretched by high-stress tightwire. The main span is 126 3 meters long with a novel structure and a unique style. In the paper,the design of basement and leaning tower structure was studied,as well as the calculation of interior force of leaning tower and tightwire being stretched. The imbalance thrust caused by dead load of leaning tower in construction was also discussed. The results well satisfy the loaded requirement of the tollgate in construction stage and in use.更多还原
