Problems solved by technology

At present, the research on fracture seepage mostly relies on the field dyeing tracer seepage test, and finally the corresponding seepage characteristics are determined through on-site excavation. Since the specific process of seepage during the test cannot be observed, its nature is similar to the black box model, which is very unfavorable. scientific research and engineering activities
At present, the research on fracture seepage at home and abroad mostly focuses on the field macroscopic scale, but less on the mesoscopic mechanism; while the research on the mechanism is mostly focused on a single fracture, and there are few studies on intersecting fractures.

Abstract

The invention discloses a visual experiment device and method for simulated cross fracture seepage. The visual experiment device comprises a cross fracture mold and a test device for observing cross fracture seepage. The inside of the cross fracture mold is of a T-shaped cross fracture structure; and the test device comprises a fixed device, a flow control device and a data acquisition device. Thetest device realizes a quantitative observation research on a transparent cross fracture seepage process by using a light transmission principle; and meanwhile, flexible adjustment of relative positions of a camera, a light source and the fracture mold is realized on a mechanical structure, so that three-dimensional real-time observation of the cross fracture seepage process is realized.

Description

technical field [0001] The invention relates to a device and a method for a fissure seepage model test, in particular to a visual test device and a method for simulating intersecting fissure seepage. Background technique [0002] Underground seepage is an important frontier basic scientific issue in the field of geotechnical engineering. It is closely related to the safety of major national projects in many fields, such as the problem of foundation seepage in water conservancy projects, the storage safety of underground oil depots in petroleum engineering, and the geological storage of carbon dioxide. , the migration of pollutants in underground media, etc. Therefore, the study of seepage in rock mass is of great significance to engineering safety assessment and hazard prevention, groundwater pollution assessment and restoration and other issues. [0003] The rock mass is composed of complete massive rocks and complex structural planes. As a relatively dense porous medium,...
