【摘要】：以超大直径盾构隧道为原型,基于3D打印技术设计并制作用于振动台试验的盾构隧道关键节点模型。探讨3D打印技术应用于盾构隧道模型设计的技术难点,如结构相似比设计与3D打印材料性质的匹配性、大型结构模型的最优化分块分段打印技术、结构模型的3D打印实现与拼装等。提出大体积结构模型拆分打印的基本原则,制作出符合试验要求的联络通道和工作井等关键节点模型,检验3D打印技术在隧道结构模型设计和制作中的可行性,并总结3D打印技术的优势和制约其推广应用的原因。
[Abstract]:Based on 3D printing technology, the key node model of shield tunnel for shaking table test is designed and fabricated based on large diameter shield tunnel. This paper discusses the technical difficulties of 3D printing applied to shield tunnel model design, such as the matching of structural similarity ratio design and 3D printing material properties, the optimization block printing technology of large structure model. 3D printing and assembly of structure model. The basic principle of split printing of mass structure model is put forward. The key node models, such as contact channel and working well, which meet the test requirements, are made, and the feasibility of 3D printing technology in the design and manufacture of tunnel structure model is tested. The advantages of 3D printing technology and the reasons restricting its popularization and application are summarized.
