Complex fractured rock mass physical model manufactured based on 3D printing productionand modeling method

Abstract

The invention discloses a complex fractured rock mass physical model manufactured based on 3D printing production and a modeling method. By using 3D printing, a complex fractured network model entity is reconstructed and a model suitable for an indoor analog simulation experiment is established; the complex fractured rock mass physical model comprises a discrete fracture network DFN model and an entity discrete joint network DFN model. Based on the 3D printing, the complex fractured network model entity can be reconstructed and the model suitable for the indoor analog simulation experiment is established, and an effective method can be provided for an indoor laboratory research on complex fractured rock mass mechanical behaviors. A reliable and effective method is provided for the rock mechanical test field by adopting fractured rock mass model reconstruction and fractured network entity model construction through the 3D printing; with the help of the 3D printing technology, the problems that modeling is difficult to conduct and the cost is high in the current complex fractured rock mass physical model indoor experiment can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering testing, and in particular relates to a complex fractured rock mass physical model based on 3D printing and a modeling method. Background technique [0002] In terms of laboratory research on rock mechanical properties, limited by complex model modeling methods, current research is mostly on rock or rock-like (gypsum, concrete) materials, and research on the mechanical behavior of similar rock materials with complex crack distribution is relatively limited. few. With the rise and progress of 3D printing technology, solid modeling of complex structures has gradually become possible. At present, 3D printing technology is widely used in medicine, machinery manufacturing, automobile and other fields, but it is less applied in rock mechanics, especially the application results in geometric modeling of complex structural surfaces are rarely reported. Since the actual rock mass is rich...
