摘要/Abstract

摘要： 本文对西安市考古公园混凝土3D打印景观拱桥的结构组成及建造方式进行介绍,详细阐述拱桥核心设计元素。拱桥设计基于混凝土3D打印路径规划重构、简化古代青铜器饰纹“雷云纹”,并将其作为拱桥的外观的主元素。结合混凝土3D打印系统的打印能力及拱桥结构特点对拱桥进行优化分块,根据结构设计需求配制打印材料,完成拱桥上部结构设计建造。基于ANSYS软件对该拱桥进行数值模拟,分析其结构强度及动力特性,计算结果表明拱桥各项性能参数符合设计要求。最后结合拱桥打印构件组装和整体安装的特点,对混凝土3D打印箱型拱桥的施工工艺进行阐述。

Abstract: 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.

Key words: concrete, 3D printing, box arch bridge, numerical simulation, printing process, construction installation
