Description

technical field [0001] The invention belongs to a moving bed muddy water model test device for sea-related engineering, in particular to a moving bed muddy water model tide-gathering auxiliary wave-making system and a control method. Background technique [0002] The solid physical model test is an indispensable scientific method for the design and theoretical research of estuary coast, offshore and other wading engineering. The offshore area is a place where tidal currents and waves act comprehensively, and the water body is often highly sandy and muddy, and the flow and sediment environment is complicated. Therefore, the engineering structures built in this area are also subjected to very complicated forces, and the resulting underwater topography The scouring and silting changes are more complex. [0003] For wading projects such as port construction, waterway improvement, coastal development, island building and revetment, under natural conditions and after the project ...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing moving-bed muddy water test devices use the moving-bed model mainly based on bottom sand, and there is less involvement in suspended sand and sand addition.

However, the experimental devices involving suspended sand and sand adding often cannot simultaneously realize the simulation of tidal wave generation, mutual coupling, synchronous matching with the tidal current, and the simulation of real water and sand movement in engineering waters. After a test, water and sand cannot be automatically separated and circulated. use

[0005] In addition, for the bay area represented by Hangzhou Bay, it is affected by incoming currents, sand, and waves from multiple directions such as Qiantang River, Nanhuizui, and the sea outside the bay. It can generate tidal flow in one direction or less directions, and its wave-making equipment can only complete the wave-making function in less directions, and its Gaza equipment cannot move freely between multiple Gaza sections at the same time, making it unable to meet the needs of multiple directions. Simulation test requirements for offshore wading projects with waves and sand

In particular, for the overall development projects of the South China Sea and Zhoushan islands, there is currently a lack of a moving bed muddy water model test device that can complete multi-directional tidal wave generation and sand generation, thereby accurately fitting the overall hydrodynamic sediment environment of the islands
