Multifunctional three-dimensional similar simulation test platform and test method

Abstract

The invention discloses a multifunctional three-dimensional similar simulation test platform and a test method, and relates to the technical field of mining and rock and soil mechanics tests. The platform comprises an analog simulation test stand used for providing force or deformation control, an analog simulation sample used for analog simulation of rock stratum structures and components, a multi-field coupling servo control integrated system used for achieving force-displacement-temperature-seepage multi-field coupling servo control, and an intelligent multi-parameter monitoring and analyzing system used for realizing whole-course evaluation of the similar simulation test. The similar simulation test equipment integrates microwave thermal rock breaking and fracturing permeability increasing technologies, and realizes organic combination of underground engineering excavation and similar simulation tests for promoting production of coal measure gas.

Description

technical field [0001] The invention relates to the technical field of mining and rock-soil mechanics test, in particular to a multifunctional three-dimensional similar simulation test platform and test method. Background technique [0002] Similarity simulation test is a commonly used test method between the field test scale and the laboratory physical test scale, and is widely used in mining, geotechnical engineering, hydraulic engineering and other fields. With the refinement of the development of related industries, the interdisciplinary phenomenon between different engineering fields has become more and more obvious. At the same time, the coupling relationship between force, displacement, temperature and other multi-field environments in engineering has become increasingly prominent. However, most of the traditional similar simulation test equipment are two-dimensional plane models, most of which are only suitable for a relatively fixed engineering background, and rarel...

Problems solved by technology

However, most of the traditional similar simulation test equipment are two-dimensional plane models, most of which are only suitable for a relatively fixed engineering background, and rarely consider factors such as temperature, true triaxial stress, and pore gas pressure.
