The new type of bridge with self-anchored cable-stayed coordination system has the characteristics of complex construction technology and difficult construction technology. In other words, it is necessary to ensure the balance of the forces on both sides of the suspension cable system and the cable-stayed system theoretically, and simultaneously monitor and dynamically adjust the construction scheme during construction. Another difficult problem is to control the installation position of the unconstrained space loose cable sleeve in the empty cable state and the offset position in the bridge state. This paper introduces the selection of the construction scheme and the concrete construction method of the superstructure of Nanping Cross-River Bridge, and provides reference for the construction of similar self-anchored cable-stayed cooperative system in the future.
