| 摘 要： | 根据室内试验结果 ,建立了一个能够统一表达圆形喷嘴和矩形喷嘴射流强度的公式 ,建立了由射流产生的冲刷坑的几何尺度与射流强度间的关系。对试验中发生的喷嘴临界提升高度从理论上分析了存在的合理性。依据分析建立的喷嘴在临界提升高度和最大提升高度之间的冲刷坑尺度与射流强度、倾角和提升高度间的关系能够较好地描述试验结果。

| Abstract: | Based on laboratory experimental results, a universal formula was established which could express the jet flow intensity both for circular and rectangular jet nozzle. The dimensions of the scour hole were correlated with the jet flow intensity. The rationality of existing a critical height for jet nozzle obtained from experiment was analyzed theoretically. Correlation established between the scour hole dimensions and the jet flow intensity, jet flow inclination angle and the height of the jet nozzle above the bed could express the experimental results fairly. |
