Description

Technical Field

[0001] This utility model relates to the field of model box internal support technology, and in particular to a flexible boundary model box internal support component. Background Technology

[0002] In existing seismic simulation experiments, model test boxes are generally fixed using rigid boundary connections, and their boundary constraints are equivalent to rigid constraints. However, in actual engineering scenarios, when tunnels, pipelines, and bridges are subjected to seismic loads, their interaction with the foundation needs to be characterized by viscoelastic boundaries to accurately reflect the actual stress state and seismic behavior of the structure. Rigid constraints cannot simulate this complex boundary interaction process, leading to significant deviations between experimental results and the actual seismic response of the structure, making it difficult to accurately verify the rationality of seismic design. Therefore, based on the above technical problems, it is urgent to conduct targeted optimization design of the boundary constraints of the model box, and to set flexible boundaries to achieve a more accurate simulation of actual seismic scenarios, providing reliable experimental basis for seismic design.
