According to the technical responsible person of the construction side of the bridge and the second Aviation Bureau of Zhongjiao, the main tower of the bridge has applied "skin function" concrete, that is, a new type of heterogeneous composite concrete material with changing properties and functional gradient. At the same time, the construction side adopted the steel beam gathering anchoring technology, and the 108 cable-stayed cables of the main tower were anchored on 6 steel beams, extending radially to the bridge body as a whole. These new materials and new techniques change the mechanical structure of the main tower of the bridge and improve the crack resistance, durability and appreciation of the concrete structure of the cable tower column.
