中文摘要	百色水电站运行时,尾水隧洞中有可能出现明满交替流动而使尾水系统对电站运行的稳定性和过渡过程都带来复杂的影响,因此建立合理可行的明满交替流动数值模型是完全必要的。针对现有明满交替流动的数值解法中存在稳定性差的缺点,提出了一种新的计算方法——特征隐式格式法,其主要思路是将动量方程和连续方程转化为双曲型方程组的标准形式进行差分,并通过尾水隧洞水工水力学模型试验专门对该方法进行验证,表明该计算方法是正确的。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。; In tailrace tunnels of Baise Hydropower Station, a transient mixed free-surface-pressure flow may occur, which has a complex effect on the stability and transient of the power plant, so it is needed to build a reasonable and feasible mixed free-surface-pressure flow numerical model. In this paper, several methods used for computing the mixed free-surface-pressure flow are compared and analyzed. Based on implicit finite difference scheme, a new method (Characteristic Implicit Format Method) with good stability has been offered. Compared with other methods, the new method solves the problem of the stability. The normal forms of the hyperbolic system made up of the continuity and momentum equations are used and differenced. The calculation results of this scheme agree with the tailrace tunnel hydraulic modeling test very well. The method is adopted in the tail-race system dynamic simulation calculation of Baise hydropower station, and the tailrace tunnel shape is optimized, so the satisfying result is worked out.
