The invention discloses a fluid flow simulation device and method in a model test of tunnel water and mud inrush, which comprises two tunnel simulation pipes parallel to each other, and the two tunnel simulation pipes are connected by a horizontal hole simulation pipe, the tunnel simulation pipe and the horizontal tunnel simulation pipe The bottom of the tunnel simulation tube is connected with a sliding body, the sliding body is placed in the track groove, and the sliding body slides freely in the track groove; three-center circular plates are arranged in the two tunnel simulation tubes, and the The above-mentioned three-center circular plate makes the fluid flow into the tunnel simulation tube according to the set water pressure and speed, and observes the flow law of the fluid in the two tunnel simulation tubes and the horizontal hole simulation tube; and by adjusting the three-center tube in the tunnel simulation tube The position of the component of the circular plate simulates the different distances between the tunnel face and the horizontal hole; by adjusting the position of the component A with the three-center circular plate in the two tunnel simulation tubes, the distance between the two tunnel faces is simulated. different positional relationships.
Description
technical field [0001] The invention relates to a fluid flow simulation device and method in a tunnel water and mud inrush model test. Background technique [0002] Tunnels involve traffic engineering (railways, highway tunnels), water conservancy and hydropower engineering (water transmission tunnels, underground powerhouses) and other important engineering fields, and have gradually become an important part of the country's major infrastructure projects. In the planning of strategic scientific and technological development, the focus of major engineering construction is gradually shifting to the western mountainous areas and karst areas with extremely complex topography and geology. High-risk tunnel projects with significant characteristics such as high-risk tunnel projects face serious risks of geological disasters such as water inrush and mud inrush during the construction process. Water and mud inrush disasters in deep-buried tunnels are often characterized by suddenne...
