摘要
两过水土石围堰导流标准和导流方案相同,在经受流量Q=3000m3/s左右的洪水后,两围堰产生了截然不同的破坏结果。从上下游堰顶高差、挑流平台高程设计及消能等方面,分析了结构物产生破坏的原因。
The damage degrees of two overflow earth-rock cofferdam with the same diversion standard and scheme were completely different after a flood with a discharge equaled 3 000m^3/s. The reasons were studied based on upstream and downstream height difference and jet flow elevation design , as well as energy dissipation mechanism.
