摘要
为了探索一条在山区大流量河流中布置经济指标较好的河床式水电站,打破常规,创新出一条新的设计思路,利用贯流(卧式)机组的上部空间作为泄洪通道,泄洪和发电建筑物重叠布置(汛期上部泄洪,非汛期下部发电),缩短建筑物前缘长度,减少两岸开挖及混凝土量,大大降低工程投资,改善经济指标。以汉江蜀河水电站为例,提供厂内溢流布置型式关键技术问题的设计和研究,为类似工程的设计提供有益的参考。
To explore one new design idea which brings through the conventional concept and can an＇ange the run-of-the-river hydropower stations with good economic indicators in high-discharge rivers in mountain area, the upper space of the tubular unit is applied for flood discharge passage, both flood outlet and power generation structures are superposed in layout （upper space for flood discharge in flood season and lower space for power generation in non-flood season）. This layout shortens the front edge length of structures, reduces excavations on both banks and concrete placement volume. This largely decreases project investment and improves economic indicators. In this paper, Shuhe Hydropower Station on the Hanjiang River is taken as an example, providing design and study of key technical points for overflow layout modes in powerhouse as well as useful reference for design of similar projects.
