Problems solved by technology

[0012] At present, in geomechanical model experiments, there are many developments and developments of similar materials for rock mass, such as mixtures made of barite powder, limestone, and epoxy resin; coated iron powder, coated quartz sand, barite powder, and rosin The mixture of alcohol solution; the mixture of magnetite powder, river sand, gypsum or cement, and water; the mixture of quartz sand, gypsum, cement and water of different particle size distribution, etc. Simulating the density and tensile and compressive strength of rock mass is relatively mature, but it has been lacking in the simulation of deformation modulus. At the same time, there is also a problem that the scope of application is narrow and it cannot simulate various types of rock mass from Ⅰ to Ⅳ.

Abstract

The invention relates to the field of geological research, in particular to a rock similar material for a geomechanics physical model test and a preparation method thereof. The material is prepared from, by weight, 45-50 parts of barite, 1.5-3.9 parts of cement, 2.4-4.5 parts of water, 1-5 parts of 46# waste hydraulic oil and 0.5-1.5 parts of rubber powder. The barite and the rubber powder are evenly mixed, and then dried and dewatered, the mixture is taken out and cooled to room temperature, the cement is added to continue to be stirred to be uniform, the 46# waste hydraulic oil is added to the mixture to be stirred to be uniform, then the water is added to be stirred to be uniform, and the material is obtained. The preparation process of the method is simple, mixing is carried out at normal temperature in the preparation process, and therefore energy consumption is low, preparation efficiency is high, and cost is low.

Description

technical field [0001] The invention relates to the technical field of geomechanical model test materials and preparation, in particular to a rock mass similar material used for geomechanical physical model tests and a preparation method thereof. Background technique [0002] With the rapid development of modern economy and science and technology, people need more and more buildings (structures) to meet the needs of daily life, such as hydropower stations, residences, industrial plants, tunnels, etc. Some of these projects need to be built in places with poor engineering geological conditions. When faced with many mechanical problems in actual engineering, the indoor geomechanics physical model test is one of the important research methods. [0003] Model test is a research method for conducting scale-down tests on specific engineering geological problems according to a certain similarity principle. Solve practical engineering problems. In the model test, similar materials...
