| 8. | Using a vortex - flow drop shaft to convey water from a high level to a diversion runnel under the condition of high water - head and large discharge is a new kind of technology in the scheme of reusing a diversion tunnel as a discharge tunnel 近年来,为解决高水头、大流量导流洞改建泄洪洞的技术难题,旋流式竖井泄洪洞逐渐成为研究热点之一。但迄今为止,该技术尚未得到推广应用,其主要原因在于人们对竖井螺旋水流运动特征缺乏足够的了解和深入的研究。 |
| 9. | Abstract : for high arch dams in valleys with the characteristics of high water head , large discharge and large power , the problems of energy dissipation and scour prevention are serious . based on scientific studies , new comprehensive measures are proposed , including dispersion of discharge to waken wallop of the current , and reinforcement of riverbed to enhance the erosion - resistance . the measures can be used to solve the problem of energy dissipation properly . a typical layout scheme has been proposed in which slotted bucket with diversion teeth , double deck with pores , and cushion pool are considered practice has proved that the scheme is reliable and the effect of energy dissipation is obvious 文摘:高拱坝泄洪消能的特点是坝高落差大,流量大,功率大,位于河谷狭窄地区,泄洪消能与防冲问题突出.经科学研究,采用“分散泄洪,削弱水流冲击力,加固河床,增强河道抗冲能力”的综合治理措施,较好地解决泄洪消能布置问题.提出了表孔大差动坎加分流齿、双层多孔、水流撞击、下设水垫塘联合消能的典型布置方案,经实践证明,方案可靠,消能效果好 |
| 10. | The projects on the downstream of river are increasing recently . the common features of these projects are low head , low frounde number , large discharge ect . the roller bucket with low - ridge is applicated on the project for energy dissipation in the condition of low fr current and low head 目前修建在河流中下游的水利枢纽工程日益增多,此类河流的泄洪消能有共同特点,即低水头、单宽流量大,考虑上游淹没、移民、河道两侧的交通等问题,不宜抬高河道水位,往往采用低堰泄流。 |
