摘要：The dam break wave is a kind of broken wave, which can destroy the downstream structures. To preliminarily investigate the mechanism of the dam break wave, a numerical model was established in this study. This paper introduce the method of the numerical model and the set up of the numerical flume. The dam break numerical flume includes a reservoir, a sluice gate, a test flume, and a structure. The dam break wave was generated by suddenly lift the sluice gate, so the water in the reservoir rushed into the test flume. The generation and propagation of the dam break in the flume was simulated and observed. The time history of the pressure impact on the structure was recorded. Results show that, the dam break wave was generated by reservoir and sluice gate. In the test flume, the dam break wave stabilized, propagated, and finally engulfed the whole structure. The time history of the pressure experienced a significant peak, fluctuated line, and a quasi-steady line.
