Abstract:In order to solve the deficiency caused by the traditional pouring method of the deck of the steel-concrete composite bridge, a new type of steel-concrete composite box girder bridge deck is innovatively proposed based on the Cuibao Road Viaduct Project of the eastern transit highway in Shenzhen, and the corresponding new construction technology is put forward to improve the construction efficiency and reduce the impact on the space under the bridge. Through the numerical analysis and calculation, it is proved that the construction period of the new bridge deck is greatly reduced in the actual project, and the impact on the traffic under the bridge is also greatly reduced, which can produce the better comprehensive benefits. The new type of steel-concrete composite box girder bridge deck successfully solves the technical problems of traditional cast-in-place concrete bridge deck construction, and brings new choices and breakthroughs for the construction of the same type of bridge deck in the future. It has the great potential and is worth popularizing and applying widely.
