Panel structure for simulating gravel dam bursting test and manufacturing method of panel structure

Abstract

The invention relates to a panel structure for simulating a gravel dam bursting test and a manufacturing method of the panel structure. The panel structure comprises a veneer layer, a waterproof layer and a protective layer, wherein the waterproof layer is arranged between the veneer layer and the protective layer; the veneer layer is stuck on the upstream surface of a simulated gravel dam in the test. The method comprises the steps of (1) manufacturing the veneer layer; (2) spraying a crystalline permeability-reducing agent onto the surface of one side of the veneer layer to form the waterproof layer; (3) spraying wear-resistant paint onto the surface of the waterproof layer by a cold gas dynamic spray method to form the protective layer. According to the panel structure and the manufacturing method, the panel structure is broken along with the bursting of the simulated gravel dam, and the bursting reason, the bursting mechanism and the dam bursting process are analyzed and researched according to the breaking occasion, the breaking process and trend as well as the fracture morphology after the breaking of the panel structure, so that the panel structure is beneficial to the prediction of bursting, the emergency measures can be taken in advance, and a more reasonable stone dam structure can be better designed.

Description

technical field [0001] The invention relates to a panel structure for simulating the failure test of a sand and gravel dam and a manufacturing method thereof, which is a multi-layer plate structure device used in a laboratory for test simulation test, and a device for making the multi-layer plate structure. Background technique [0002] Sand and gravel are widely distributed and have high compressive modulus, shear strength and deformation modulus, and are a high-quality natural material for filling face dams. Nowadays, the number of face-face gravel dams in my country has reached a certain scale, among which 22% of face-face dams have been built with sand and gravel as the main dam material, and those under construction account for 23%. In recent decades, on the one hand, the number of concrete face gravel dams has increased significantly, and on the other hand, the height of dam construction has continued to break through. The proposed Dashixia face gravel dam will be as h...

Problems solved by technology

At present, the gypsum material is used in the test, but it is a brittle material. Once it breaks, the cracks are difficult to control, and the fracture will also show an extremely irregular shape, which will have a great impact on the water flow, which will cause the test to fail. In the dam failure accident, the panel showed a horizontal fracture, and the fracture was neat
