| 摘 要： | 在凤凰水库除险加固工程中,因受地形、地质条件的影响和限制,改建溢洪道的陡槽段需按转弯布置。为了削减陡槽转弯段冲击波的不利影响、有效控制最大横向水面差,以尽量减小边墙高度并获得较好的结构受力状态,该文提出在陡槽转弯段设置两道导流墙、并采取渠底超高法的组合设计方案。通过实践应用证明,该方案对改善陡弯水流流态与流速分布十分有效,可供其他类似工程参考借鉴。

| Abstract: | In the danger control and reinforcement of Fenghuang Reservoir,the chute section of spillway needed to be arranged in bending-type due to the influence and restriction of topographic and geological conditions.In order to eliminate negative effect of shock waves of curved chute,control the maximal transverse water-surface difference and reduce the height of side wall to get better operation condition for structure,we proposed the design scheme of setting two guide walls combined with super-elevation canal be... |
