摘要
本文推荐了计算尾水隧洞临界长度公式,并与国内外有关公式进行了比较、论证,认为国内现用公式偏于保守,建议用补气的方式替代尾水调压室,并推导出了补气量与通气孔的计算方法。
In present paper a formula for the critical length of tailwater tunnel has been proposed and compared with those used by engineers at home and abroad. The results show some formulas applied in our country are conservative. The writer has proposed a new way that tailwater surge tank can be substituted by an air hole through which air is compensated. And a caculation method for air compensation and air holes has been derived.
