The invention relates to a device and a method for positioning an attitude of stratum in a model test. The device and the method for positioning the attitude of stratum in the model test have a simple structure, are convenient to use, are realistic in simulation, and can be applied to a control device for model tilting and padding an attitude of rock in the model test, so that the attitude and the layer thickness of a similar material layer are manually controlled in a model padding and tamping process, the tilting and the padding in the model test are realized to simulate different geological conditions, the manufacturing of different lithological interlayers can also be realized, and thus the simulation of actual stratum conditions such as pendage, soft intercalated layers and the like in an underground engineering in the model test is favored. The device for positioning the attitude of stratum in the model test comprises main positioning plates, and an accessory positioning plate A and an accessory positioning plate B which are arranged on the two ends of the main positioning plates through a longitudinal spindle I and a longitudinal spindle II, so that dip angles between the main positioning plates and the two accessory positioning plates can be adjusted; a horizontal positioning shaft A and a horizontal positioning shaft B are arranged on the upper parts of the main positioning plates and are connected with a model support; and a main slide bar is arranged at the lower parts of the main positioning plates, and the main slide bar, the horizontal positioning shaft A and the horizontal positioning shaft B are respectively arranged in respective linear bearings.
Description
technical field [0001] The invention relates to a geomechanics technique, in particular to a device and a method for locating stratum occurrences in model tests. Background technique [0002] With the development of my country's economy, science and technology, and the rapid development of transportation, the development and utilization of underground space has increasingly reflected huge economic and social benefits. The development and utilization of underground space in my country is developing in a modern and scientific direction. With the continuous increase in the number and scale of underground projects, many scholars are studying the optimization of underground engineering design and construction methods in various ways, and exploring the mechanical laws of the construction process. Among them, model test is one of the effective methods to study the law of underground engineering construction process. [0003] The model test is based on the similarity theory, transf...
