The steel tube tower structure is widely used in the wind power industry. The tower, as the main bracing member, is characterized by simple and beautiful architectural appearance, simple structural form, and convenient construction. However, the steel tube tower structure has not been applied to the existed navigation mark engineering. In order to promote the application of the steel tube tower structure in port’s navigation mark engineering and similar inland river engineering, this paper presents the connecting method of steel tubes, jointing of the tube with the foundation, as well as the type selection of the foundation, and expounds the design and calculat ion of the navigation mark of steel tube tower structure based on the engineering examples which have been completed.
