Abstract

The invention relates to a device for simulating dike and dam break waves on steady flow, and belongs to the technical field of experimental devices for dam break wave research. The device for simulating the dike and dam break waves on the steady flow comprises a water tank, a gate installed in the water tank and a lifting device for controlling the gate to ascend and descend. The device is characterized in that the gate comprises a gate plate body, a steady flow water hole for forming steady flow is formed in the lower portion of the gate plate body, the steady flow water hole is a stepped hole with the T-shaped cross section, an overflow opening for water overflow is formed in the upper portion of the gate plate body, and water gate openings for water gates in a water gate device to transversely move are formed in the two sides of the overflow opening; the pair of water gates installed in an overlapped mode is installed in the overflow opening, and the dam break waves of a dam body in different notch states are simulated by controlling the distance between the two water gates.

Description

technical field [0001] The invention relates to a device for simulating a dam breaking wave on a steady flow, and belongs to the technical field of experimental devices for dam breaking wave research. Background technique [0002] According to the "First National Water Conservancy Census Bulletin" issued by my country in 2013, there are a total of 98,002 reservoirs of various types in my country, of which the storage capacity exceeds 100 million m 3 There are more than 400 large reservoirs in China. Within the scope of our country's reservoir protection, there are hundreds of large and medium-sized cities, more than 300 million people and 480 million mu of farmland. With the passage of time and the lack of routine maintenance, the dam body of the reservoir will inevitably experience aging and damage, forming dangerous reservoirs and disease reservoirs. Extreme events such as earthquakes and heavy rains are likely to induce dam failures and cause huge safety hazards. Hidden...
