The invention provides a wave-flow coupling test device suitable for simulating the underwater multi-point earthquake input, comprising: two reservoirs, a test water tank, a flow making platform, theflow making platform, a wave maker, a vibrating table located in the test water tank and a wave dissipating plate. The wave-flow coupling test device is characterized in that: one of the two reservoirs is a main reservoir, and the other is an L-shaped reservoir. The flow making platform is positioned at the one side of the L-shaped water reservoir, which is approach to the main reservoir. A secondvertical baffle opened with an opening is provided on the flow making platform. The flow maker is positioned on the flow making platform between the two vertical baffles, and the outlet is communicated to the opening in the second vertical baffle. The main reservoir is communicated with one side of the bottom of the test water tank, and the flow making platform is communicated with the other sideof the test water tank. An opening area is reserved on the middle position of the bottom of the test water tank, and is provided with the vibrating table. The wave maker and the wave dissipating plate are located at two sides of the test water tank respectively. According to the wave-flow coupling test device suitable for simulating the underwater multi-point earthquake input, multi-point seismicexcitation can be performed, and a seismic-wave-water flow coupling effect can also be realized.
Description
technical field [0001] The invention mainly relates to the field of earthquake prevention and disaster reduction in civil engineering and water conservancy engineering, and in particular relates to a wave-current coupling test device suitable for simulating underwater multi-point earthquake input. Background technique [0002] In 2018, the first national major scientific and technological infrastructure in the field of earthquake engineering in my country - a large-scale multi-point earthquake engineering simulation research facility, was led by Tianjin University. The total construction area of the device is expected to reach 77,000 square meters, and the construction period is 5 years. After the completion of the construction, it will provide an effective platform for the seismic research of the world's major projects. In this context, some long structures (such as: cross-sea bridges, subsea tunnels and large hydropower stations, etc.) need to consider the multi-point fl...
