Abstract
The invention provides a multi-functional stratum structure model test system and test method. The system includes a test piece test device platform, which is composed of a watertight fan-shaped closed cavity, fluid-solid coupling loading, and an anti-arc reaction force frame; coupling The loading system area includes hydraulic (liquid) loading and multi-directional loading of the specimen skeleton to the pore-crack specimen, both of which can be independent or combined with each other; the sector-shaped closed cavity is fixed by the reaction force frame system, and the sector-shaped The central area of the circle can be set as the construction area of the underground working face, and the other two flat sides can be set as the physical and chemical improvement construction area for the surrounding rock. The test piece processing platform is based on the future development of 3D printing. The template is made of inorganic materials such as tempered glass that are consistent with the performance of the test piece. It can be removed or not, but the outer surface of the test piece is smooth to meet the sealing requirements. The test method is synchronized with the numerical model, and all kinds of complex underground engineering model tests and related theoretical research are carried out with the policy of "full scale and strict science".
Description
technical field [0001] The invention relates to the technical field of stratum structure model test research, in particular to a multifunctional stratum structure model test system and test method. Background technique [0002] With the development of urban underground space and deep resources, the design, construction and technical difficulties of underground engineering under complex geological conditions are increasing. The mechanical performance test of underground engineering structure is restricted by theoretical and technical conditions. The "load + structure" test mode of ground building structure has been used for a long time. The loading method is direct loading in one direction with a simple mechanical jack. However, in fact, underground engineering structures are different. Based on the ground structure, its main features are: [0003] 1) The existence of surrounding rock is not only an external load, but also a part of the bearing structure; [0004] 2) Underg...
