Description
技术领域technical field

背景技术Background technique
利用相似材料制作模型试样进行力学试验是工程研究的重要手段，岩石结构面抗剪强度试验受原岩试样取样成本高、周期长，样本少，国内外不少学者都采用相似材料开展岩石结构面力学性质的研究。而对于岩石结构面而言，影响岩石抗剪影响强度的主要因素有岩石的强度及结构面表面的起伏形态，活性粉末混凝土(主要由砂、水、水泥、硅粉、减水剂等组成)由于在破坏关系与岩石材料较为一致，而且能较好地模拟岩石结构面的起伏形态，因此在工程中较多采用活性粉末混凝土制作模型试件开展力学试验。但受模拟材料的影响，制作完成的模型试样表面存在较多的孔隙(直径约为1-2mm)，且在制作过程中无法避免，影响岩石表面的起伏形态和粗糙度系数的测量精度。因此，如何找到一种材料，对试样的表面孔隙进行填补，使得与试样具有较好的融合，且不会破坏结构面原有的表面形态，是模型试样制作亟需解决的一个问题。Using similar materials to make model samples for mechanical tests is an important means of engineering research. The shear strength test of rock structural surfaces is limited by the high cost of sampling original rock samples, long cycle, and few samples. Many scholars at home and abroad use similar materials to carry out rock tests. Research on mechanical properties of structural surfaces. As for the rock structural surface, the main factors affecting the shear strength of the rock are the strength of the rock and the undulating shape of the surface of the structural surface, and the active powder concrete (mainly composed of sand, water, cement, silica fume, water reducing agent, etc.) Since the failure relationship is more consistent with the rock material and can better simulate the undulation of the rock structural surface, reactive powder concrete is often used to make model specimens for mechanical tests in engineering. However, due to the influence of the simulated material, there are many pores (about 1-2 mm in diameter) on the surface of the finished model sample, which cannot be avoided during the production process, which affects the undulation shape of the rock surface and the measurement accuracy of the roughness coefficient. Therefore, how to find a material that can fill the surface pores of the sample so that it can be well integrated with the sample without destroying the original surface morphology of the structural surface is a problem that needs to be solved urgently in the production of model samples. .
