Control system and method for hydraulic boundary conditions of water inrush and mud inrush in model test

Abstract

A system and method for controlling hydraulic boundary conditions of water inrush and mud inrush in a model test, comprising: a control water tank, one side of the control water tank is connected to a water pump through a water inlet pipe, and the water pump is arranged in an external water collection tank; the inside of the control water tank Set water baffle A and water baffle B, said water baffle A and water baffle B divide the control water tank into E1, E2, E3 three districts in turn; The water pressure converter is placed at the entrance of the tunnel, and a collection device is installed under the exit of the tunnel. The collection device communicates with the external water collection tank through the return pipe A; the bottom of the control water tank E3 area is connected to the external water tank through the return pipe B. Beneficial effects of the present invention: the water in the device can be recycled, saves water resources, is made of high-strength transparent resin material, has good visibility, and the setting of the hydraulic pressure converter can adjust water inrush and mud gushing under certain flow conditions water pressure at.

Description

technical field [0001] The invention relates to a geomechanics test technology, in particular to a control system and method for hydraulic boundary conditions of water inrush and mud inrush in model tests. Background technique [0002] During the construction of the tunnel, there are serious risks of geological disasters such as water inrush and mud inrush, especially the water and mud inrush disasters in deep tunnels are often characterized by suddenness, large flow, and high water pressure. Once a disaster occurs, the tunnel will be submerged at least , The construction is interrupted, and it will cause heavy casualties and economic losses, and even some projects have to be suspended or rerouted. Scholars at home and abroad have done a lot of theoretical and model test research on the disaster-causing mechanism of water and mud inrush disasters and the characteristics of the displacement field, stress field and seepage field during the catastrophe evolution process. There...
