一种基于3D打印的单裂隙岩体试件的制作方法
摘要：
本发明公开了一种基于3D打印的单裂隙岩体试件的制作方法，包括：步骤1：绘制单裂隙的三维数字模型和试件模具的三维数字模型；步骤2：基于单裂隙的三维数字模型和试件模具的三维数字模型，分别3D打印单裂隙模型和试件模具；步骤3：利用单裂隙模型和试件模具，通过浇筑水泥砂浆制成单裂隙岩体试件。本发明的基于3D打印的单裂隙岩体试件的制作方法，通过三维建模技术和3D打印技术获得单裂隙模型和模具模型，通过水泥砂浆浇筑获得单裂隙岩体试件，避免了野外取样时试件产生新的裂缝增大实验误差，以及天然岩样压裂后岩石破损无法进行重复性实验的问题，且加工精度高，确保单裂隙岩体试件的精准，提高了流体在裂隙渗流特性研究的准确。
摘要（英）：

The present invention discloses a method for manufacturing a single-fracture rock specimen based on 3D printing, including: step 1: drawing a three-dimensional digital model of a single fracture and athree-dimensional digital model of the specimen mold; step 2: respectively performing 3D printing on a single-fracture model and the specimen mold based on the three-dimensional digital model of thesingle fracture and the three-dimensional digital model of the specimen mold; and step 3: manufacturing the single-fracture rock specimen by pouring cement mortar by using the single fracture model and the specimen mold. In the present invention, in the method for manufacturing a single-fracture rock specimen based on 3D printing, a single fracture model and a mold model are obtained through a three-dimensional modeling technology and a 3D printing technology, and a single fractured rock specimen is obtained by pouring cement mortar, so as to avoid a problem that an experimental error is increased because a new fracture is produced when the specimen is sampled in the field, and repetitive experiments cannot be performed due to the rock breakage of natural rock sample, and processing precision is high, so that accuracy of the single-fracture rock specimen is ensured, and accuracy of a study of characteristics of fluid seepage in the fracture is improved.
