| 摘 要： | 为研究影响射流冲刷的因素，作者进行了７０组试验，分别研究了单管和多管，水平和有入射角，贴底和离开床面，静水和动水等情况。对试验结果的分析表明，在床沙一定、河流流速与射流流速相比不大的情况下，冲刷坑的几何尺寸与Ｖ＾２／３Ｄ＾５／６有较好的关系。

| Abstract: | To study the factors that may affect the scour by water jet, the authors have carried out 70 sets of experiments. The cases of single jet and multiple jets, horizontal jet and inclined jet, wall jet and elevated jet under the conditions of still and flowing water have been investigated. Experimental results show that the dimensions of the scoured hole correlate fairly with V 2/3 jD 5/6 when the bed material is given and the velocity of the river flow is insignificant as compared with the jet flow. |
