| 摘 要： | 在狭窄河谷下修建高坝水电站,高速水流如何下泄至下游河道,如何保证大坝的安全,如何减少对环境的影响,泄水建筑物的布置形式极其重要,要对泄水建筑物的布置进行系列研究.对某典型深窄峡谷高坝水电站泄水建筑物体形优化试验研究,结果表明:原体形方案泄水时水舌分布不合理,并且对消力池的冲刷很严重,在较大下泄流量时,消力池的覆盖层几乎被冲掉,直冲基岩,不值得借鉴,经过体型优化,推荐的优化体形能很好地解决上述问题,试验研究成果可供类似工程参考.

| Abstract: | There are many problems on the construction of high dams in narrow valleys,such as how the high-velocity flow excretes to downstream rivers,how the safety of the dam is ensured,and how the impact on the environment is reduced,so the design of the discharge structure is extremely important.Thus a series of experiments based on a practical project with typical deep narrow valleys are carried out to investigate the problem of shape optimization.The results indicate that the distribution of the nappe is unreaso... |
