Abstract
A method for making an intermittent rock sample model without filling fractures, comprising the following steps: (1) determining the bone of the rock model according to the geometric similarity ratio, strength similarity ratio and elastic modulus similarity ratio between the rock block sample and the model; (2) Cut thin flake water-soluble paper, and then apply paraffin wax on its surface; (3) Fix the water-soluble thread paper in the sample preparation mold with water-soluble thread; Weigh the mixing ratio and mix evenly, and pour it into the sample mold in layers; (7) put the sample and the sample preparation mold into the oven for heating; (8) take the sample out of the sample preparation mold, and use The boiling method saturates the sample. After the sample is saturated with water, the water-soluble paper interacts with the water; (9) Take out the sample, place it in a ventilated, cool, and dry place, and let it dry naturally. The invention has the advantages of simple principle, convenient operation, low cost, good forming effect, and can fully consider the spatial position of rock mass fissures.
Description
technical field [0001] The invention relates to a method for making a rock sample, in particular to a method for making a rock sample that can consider the non-filling condition of the internal cracks of the rock mass, and is suitable for the experimental study of the influence of the development characteristics of the cracks without filling on the physical and mechanical properties of the rock mass occasion. Background technique [0002] The existence of fissures in the rock mass destroys its integrity and continuity, and the strength of the rock mass is much lower than that of the rock. Due to the differences in the geometric shape, filling properties and spatial distribution of the fracture surface, there are obvious differences in the strength and deformation characteristics of the rock mass. [0003] At present, experimental research is an important research method to analyze the deformation and strength characteristics of fractured rock mass. However, considering the...
