Abstract

The invention provides a device and method for producing fiber grating model geogrids based on 3D printing. The device comprises a computer system and model geogrid printing equipment, wherein the model geogrid printing equipment comprises a printer rack, a geogrid raw material supply assembly installed on the printer rack, a spray head moving assembly, a spray head arranged at an end of the geogrid raw material supply assembly, a printing platform arranged below the spray head and the spray head moving assembly. According to the device and method for producing the fiber grating model geogrids based on 3D printing, fiber gratings are packaged in the model geogrids through the 3D printing technology, the problem of rib material stress measurement in a reinforced soil structure model test is solved, and precise measurement of model geomaterial deformation and internal force is achieved.

Description

technical field [0001] The invention relates to the field of geotechnical engineering model tests, in particular to a device and method for preparing fiber grating model geogrids based on 3D printing. Background technique [0002] Geosynthetics are widely used in geotechnical engineering because of their high tensile strength, strong ability to adapt to deformation, and low cost. The reinforced soil structure is to improve the overall stability of the reinforced structure and reduce the deformation by pre-embedding geosynthetic materials, such as geomembrane, geogrid, geocell, etc., into the soil and reinforcing the soil. Effect. [0003] However, in the current design process of reinforced soil structures, its theoretical research often lags behind engineering practice, resulting in conservative engineering design. Many accidents and failures have different reasons for post-event analysis and summary, prompting engineering designers to pay more attention. keep. The essen...
