| 摘 要： | <正>漂木道是木材水运单漂水力过坝的一种构筑物。在上文中,我们曾对漂木道设计中的坡度、出口条件以及弯道超高等因子进行研究并取得了一定的成果。但由于上述研究中漂木道的底部设有三人字形加糙齿,水工模型试验和生产现场的原型观测都发现三人字形的加糙齿引起三股明显的翻花水,使水流渗气严重,大量单漂原木撞击漂木道槽底。因此,需要对加糙齿的形状作进一步的研究。

| Abstract: | A flume is a hydroengineering building by which floating logs cross the dam of the hydropower station. Roughs are the device fixed on the bottom of the flume to regulate the drifting of logs. The purpose of this experiment is to find the optimum shape of the flume roughs.Two types of flume roughs are tested in our experiment, one in linear form and the other in the shape of "W" horizontally. Results show the linear form rough gives better hydraulic effect than the "W" shaped one. |
