Design method for mix proportion of similar material for 3D printing of rock mass model
The invention relates to a rock mass model 3D printing similar material mix proportion design method, and belongs to the technical field of rock soil/underground engineering physical simulation similar materials. The method comprises the following steps: firstly, determining basic physical properties, mechanics, seepage, thermology and crustal stress occurrence environments of rocks in a rock prototype; then according to a fractured rock mass prototype and a similar scale, determining parameter requirements required by a model material, screening material types and determining a mixing amount range; designing a proportioning scheme through an orthogonal design method, pouring a sample, testing physical and mechanical parameters of the sample, and primarily selecting an available printing proportion; and printing parameters are optimized and checked, and finally the material ratio and the printing parameters are determined. The mix proportion design method provided by the invention provides theoretical and material basis for large-scale three-dimensional fractured rock mass physical model preparation and geomechanics research.
本发明一种岩体模型3D打印相似材料配合比设计方法，属于岩土/地下工程物理模拟相似材料技术领域。首先明确岩体原型中岩石基本物理性质、力学、渗流、热学以及地应力赋存环境；然后根据裂隙岩体原型和相似比尺，确定模型材料所需的参数需求，筛选材料种类和确定掺量范围；再通过正交设计法设计配比方案，浇筑试样，测试试样物理力学参数，初选可用打印配比；优化打印参数并检验，最终确定材料配比及打印参数。本发明提出的配合比设计方法为大型三维裂隙岩体物理模型制备及地质力学研究提供理论和材料基础。
