Description

technical field [0001] The invention belongs to a muddy water wave test device for offshore engineering, in particular to a mobile sand-gathering wave-making muddy water model test device and method with automatic sand cleaning function. Background technique [0002] The solid physical model test is an indispensable scientific method for the design and theoretical research of wading engineering in coastal areas such as estuaries and coasts. The current, wave, and sediment environment in the offshore area is complex, and the stress on engineering structures and the erosion and deposition changes in the waters near the structures are also very complicated. [0003] For wading projects such as port construction, waterway improvement, coastal development, island building and revetment, under natural conditions and after the project is implemented, the erosion and silting of underwater terrain and the stress of engineering structures are all to be studied during engineering desig...

Problems solved by technology

[0004] The existing wave test device in muddy water cannot realize the simulation of the amount of sand added synchronously with the wave, and the coupling with the wave-making system often cannot meet the test requirements. After one test, it cannot automatically settle sand, clear sand and circulate use

In addition, for the archipelago terrain represented by the Zhoushan Islands, it is affected by incoming sand and waves from multiple direction...
