| 摘 要： | 在托马假定前提下,从调压室基本方程入手,推导复杂尾水系统的尾水调压室稳定断面计算公式,并通过工程实例进行验证.计算结果表明,尾水调压室断面面积随水轮机工作水头的增大或尾水洞长度的缩短而减小.这和理论分析是一致的.

| Abstract: | Based on Thoma supposition and basic equations of surge tank, a few formulas were proposed for the stable sectional area of tailrace surge tank on complicated tailrace system. The calculated result from an example shows that the stable sectional area reduces with the increase of working head, or the decrease of the tailrace tunnel length. This is in agreement with theoretical analysis. |
