我省在水庫輸水道設計中,有多处采用泄洪发电合用一个输水道(簡称二洞合一)的形式。这种形式具有很多优点,如工程量少,工程布置集中,管理方便等;但通过几年来的实际运用,也发現不少問題。現根据西大洋、安各庄、崗南三个水庫輸水道的实际运用及模型試驗結果,对二洞合一問題进行初步分析,并提出一些看法,供有关单位研究参考。 In our province, in the design of reservoir waterways, there are many forms of flood diversion and power generation combined with a waterway (referred to as two holes in one). This form has many advantages, such as less engineering, centralized engineering arrangement, convenient management and so on. However, many problems have also been found through practical application over the past few years. Based on the practical application of the waterway of the three reservoirs in West Ocean, Ange Zhuang and Gangnan and the model test results, a preliminary analysis on the integration of two holes is made and some suggestions are put forward for the reference of relevant units.
