Visualization system for simulating excavation of fluid-structure interaction tunnel

摘要

A visualization system for simulating excavation of a fluid-structure interaction tunnel includes a fluid-structure interaction tunnel model system, a tunnel model solution supply system, a detection system and an excavation system. The tunnel model solution supply system is configured to inject a nuclide solution to simulate a fluid pressure. The detection system is configured to detect a 3D deformation state of a tunnel surrounding rock and a 3D migration process of the nuclide solution. The excavation system is provided between the detection system and the tunnel model system to simulate tunnel excavation. During the tunnel excavation, a lifting device in the excavation system controls a drilling device to ascend to a set height for operation. During 3D detection, the lifting device controls the drilling device to descend to an initial height to avoid affecting the detection of a detection device.
