The calculated result from an example shows that the stable sectional area reduces with the increase of working head, or the decrease of the tailracetunnel length.
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。

The method is adopted in the tail-race system dynamic simulation calculation of Baise hydropower station, and the tailracetunnel shape is optimized, so the satisfying result is worked out.
将该方法应用于百色水电站的尾水系统动态仿真计算中，并对尾水隧洞洞型进行优化，得到了满意的结果。
