Document Type and Number:
WIPO Patent Application WO/2024/104334
Kind Code:
A1
Abstract:
The present invention provides a high-water-pressure Trapdoor model test device and a use method. The high-water-pressure Trapdoor model test device comprises a PIV analysis unit, a liquid material, a solid material, a pore water pressure gauge, a first soil pressure sensor, a second soil pressure sensor, a third soil pressure sensor, a test chamber, and a pressurizing unit. A body of the test chamber is provided with an opening, and the opening is closed by a base plate. The base plate is provided with a hole. A trapdoor is provided at the hole and can move up and down. The third soil pressure sensor is arranged in the trapdoor. The first soil pressure sensor is arranged in the base plate. A solid material is added on the base plate. The second soil pressure sensor and the pore water pressure gauge are arranged in the solid material. A liquid material is added on the solid material. A set space is reserved between the liquid material and the inner wall of a top cover of the body of the test chamber and configured to be filled with gas. The present invention has the following beneficial effects: the formation and evolution mechanisms of soil arches under high water pressure conditions can be explored.
