Embodiment Construction

[0021] The tank structure that the present invention adopts is provided with undulating seabed such as Figure 1 to Figure 4 As shown, the opening of the U-shaped pipe 8 is set vertically upwards, and its right end is open and communicated with the atmosphere. A pressure sensor 9 is arranged at an appropriate height. A control valve 3 is arranged between the U-shaped pipes 8, and a seabed model installation section 20 is arranged in the middle of the bottom section of the U-shaped pipe 8. The seabed model 14 is installed in the installation section 20, and a laser is arranged above the seabed model installation section 20. Sheet light source 7, one side of seabed model installation section 20 is provided with a video camera 16 (see image 3 ).

[0022] The housing 18 of the control valve 3 is made integrally with the U-shaped pipe 8, and a valve plate 6 is installed in its inner chamber through the rotating shaft 4, and a stepping servo motor 17 is provided on the outer surfa...

Abstract

The invention discloses a modeling method for transferring sand in submarine that includes the following steps: spreading a layer of sand equally on the bottom of the flume; pouring water into the flume; driving water to surging and ensuring he water forms burble; using laser light source and sending the light to the middle section of the surface sand layer and capturing the image information by a camera; after a fully surging time, the sand is fully transferred to the two sides of the flume and stop surging. The invention supplies theory basis for researching to the transferring situation of shoaling sea area.

Description

technical field [0001] The invention relates to a method for simulating sediment transport in a wavy bottom bed in a shallow sea area. Background technique [0002] Field observations show that there are wavy sand bodies of various scales on the bottom of shallow waters, most of which are asymmetrical. Under the action of hydrodynamic forces such as tidal currents and waves, these asymmetric wavy sand bodies are unstable and move at a certain rate. Transport direction. This brings a series of problems. For example, the pipeline passing through the sand wave area may be exposed or even suspended. Channels can become blocked by nearby sand waves moving. From the perspective of safety and economic interests, the optimization of pipeline safety and buried depth, the profit and loss of waterway operation and dredging costs, etc. are the most important concerns of investors. Therefore, it is particularly important to study the sediment transport under the asymmetric wavy bed....
