This paper introduces the structural composition and construction method of the concrete 3D printed landscape arch bridge in Xi’an Archaeological Park,and elaborates on the core design elements of arch bridge. Referring to the traditional Chinese decorative pattern “Thunder Cloud Pattern”,a unique arch bridge appearance was printed through the path planning technology for concrete 3D printing. Based on the stress characteristics of the superstructure and considering the application range of concrete 3D printing system,the arch bridge was optimized and divided into blocks. In order to meet the structural design requirements,the printing materials were specially processed to complete the construction of arch bridge superstructure. Simulation analysis was conducted on the arch bridge using ANSYS software to examine its structural strength and dynamic characteristics. The calculation results indicate that the performance parameters of arch bridge meet the design requirements. In the end,this paper elaborates on the construction technology of concrete 3D printed box arch bridge,including arch bridge printed component assembly and overall installation.
