基于3D打印技术的盾构隧道模型设计与制作
Design and fabrication of shield tunnel models based on 3D-print technology
摘要
Abstract
Taking large-diameter shield tunnels as the prototype target, this paper first applied the 3D-print technology in the design and fabrication of shield tunnel models, including the critical parts (i.e. connecting passage and working shaft) used for shaking table tests. The technical difficulties of application of 3D-print technology in shield tunnel model design were systematically discussed, e.g. how to match the properties of 3D-print materials to the similitude ratio design, how to divide a large structure model into smaller pieces to fit the size limitation of the 3D-print machine, how to realize 3D-print model parts and assemble them together. Finally, the basic principle of optimal 3D-print technology for large-scale structural models was proposed, and the tunnel model with critical connection parts were deigned and fabricated. Results show that the fabricated modelsusing the proposed 3D-print technology perfectly satisfy the requirements of the test. Therefore, the feasibility of the application of 3D-print technology in design and fabrication of tunnel structure models is fully validated. Advantages and limitations of the 3D-print technology are also summarized.关键词
