Full-transparency fabricated multifunctional geotechnical engineering model case capable of achieving three-dimensional dimension adjustment

Abstract

The invention discloses a full-transparency fabricated multifunctional geotechnical engineering model case capable of achieving three-dimensional dimension adjustment. The model case comprises a steelbottom plate, a steel framework and soil blocking face plates. The steel bottom plate is located at the bottom of the model case. The steel framework is located on the periphery of the model case andis composed of steel angles and steel channels. The soil blocking face plates are located in the model case and are composed of corner organic glass modules and conventional organic glass modules. According to the model case, transparent organic glass modules are adopted as the soil blocking face plates, full transparency of the model case can be achieved, and it is beneficial to visualization ofthe whole process of deformation of a test model structure and soil changes on the periphery of the test model structure in the model case. Meanwhile, the transverse and perpendicular dimensions of the model case can be adjusted by adjusting overlapping of the outer framework and the number of soil blocking face plate module units. The model case can be used for developing relative tests such asthe influences of tunnel excavation on existing buildings and influences of ground stacking on subway structures. The model case has the advantages of being fully transparent, capable of adjusting thedimensions in three dimensions, convenient and fast to disassemble and assemble and rich in function.

Description

technical field [0001] The invention belongs to the technical field of test equipment, and in particular relates to a fully transparent assembled multifunctional geotechnical engineering model box which can be adjusted in three dimensions. Background technique [0002] With the rapid development of my country's economy and the improvement of the level of modernization, major cities have successively planned and built rail transit projects. Compared with ground transportation projects, underground rail transit projects have high cost, long service life, and complex stress. Research on the structure of underground rail transit The mechanical characteristics of the system are of great significance to the protection of urban traffic functions. [0003] Similarity model test is one of the commonly used research methods in the field of engineering structures. Based on the principle of similarity, this type of test makes a model that is similar to the prototype but scaled down for e...
