| 摘 要： | 根据水槽中淹没丁坝群的水流流态,将下坝附近的水流进行分区,导出淹没丁坝下游主槽流速沿程变化公式,并且结合由淹没单丁坝时得出的水头损失计算公式,可以对不同坝长、坝高和丁坝间距、淹没丁坝群的局部水头损失进行计算.

| Abstract: | Based on the flow pattern effected by submerged dikes, the flow is divided into regions near dike. Formulas used to determine the local head losses of single submerged dike and the mean velocity of main channel varying with distance downstream are derived. And using the above formulas, the head losses of non-isolength submerged dikes are obtained. The results of the computation show good agreement with the measured values in the flume. |
