为了克服天然关节试件表面形态相同的不足进行实验研究，我们提出了一种以计算机辅助设计(CAD)为桥梁的自然关节试件复制的技术方法，该方法结合了三维扫描和3D打印两种先进技术。该方法使用光学扫描设备和CAD技术重建具有天然岩石节理形态的虚拟节理试件，然后由3D打印机基于虚拟节理试件制造物理模型，以快速准确地浇注混凝土或塑料试件。质量验证表明，该方法减少了因含有自然关节形态的复制试件之间的差异而产生的实验误差。(C)2015爱思唯尔有限公司。保留所有权利。
In order to overcome the deficiency of natural joint specimens with the same surface morphology for experimental studies, we present a technical method for replicating natural joint specimens that incorporates two advanced techniques - three-dimensional (3D) scanning and 3D printing - using computer-aided design (CAD) as the 'bridge'. This method uses an optical scanning apparatus and CAD techniques to reconstruct a virtual joint specimen with the natural rock's joint morphology, and a 3D printer then manufactures a physical mould based on the virtual joint specimen for casting concrete or plastic specimens quickly and accurately. Quality verification clearly indicated that this method reduces the experimental errors originating from the discrepancies between replicating specimens containing natural joint's morphology.
