摘 要:推算不同重现期内最大冰厚度是寒区水工设计的一个关键内容。频率分析中用到的离均系数和模比系数的传统计算过程很复杂,但利用Excel内置函数GAMMAINV可以快速求解。结合黑龙江省红旗泡水库56个冬季最大冰厚度数据,利用Excel图形处理功能绘制海森概率坐标纸,进行频率计算、绘制经验频率数据点,并运用P-III型曲线推算出不同重现期的最大冰厚度值,为今后该地区冰工程设计提供了科学依据。该方法不需要编写程序,其操作过程简单,而且输出成果美观实用。It is a key content of hydraulic engineering design that the largest ice thickness of different return period was calculated in cold regions. In frequency analysis, the traditional calculation process of coefficients of deviation from mean and modulus coefficient values was complex. It used to be solved quickly by using Excel inner function GAMMAINV. In this paper, combining with 56 maximal ice thickness data on the Hongqipao Reservoir in winter, the Excel artwork treatment function was made use of drawing Hyson probability coordinate paper, calculating the frequency, drawing the experience frequency data-point, the largest ice thickness of different return period was calculated by use of P-III-type curves, scientific basis was offered for the ice engineering design in the future. The method does not require programming, its procedure is simple and easy to study, and the achievement of export is esthetical and practical.
