摘要
迷宫堰是无闸门溢洪道控制堰中深受欢迎、很有特点的堰型 ,其泄流能力强 ,但影响因素较多。本文通过试验研究和理论分析给出的流量系数公式可以很好地确定其泄流能力 ;通过水力学和结构动力学“合二为一”的水弹性模型 ,对迷宫堰的抗震性能和流激振动进行了试验研究 ,结果令人满意 ,足以为规划设计提供参考。
Labyrinth weir has special hydraulics characteristics among the uncontrolled spillway and is a popular type of weir.Its discharge capacity is greater than that of others but has a lot of influence factors. Based on the theoretical analysis and the model experiment,the formula of discharge coefficient to determine the discharge capacity is carried out in this paper. By means of the experiment of hydroelastic model,the characteristics of flow induced vibration and anti seismic capacity is studied. The result is satisfactory and it can be provided for the reference of design.
