本文对掺气分流墩墩头脉动壁压采用中心及无量纲处理，用堆排序法及本文提出的最佳区间划分法进行频率等参数的统计计算，通过经验概率密度、分布函数与标准概率分布比较，依据格利文科定理判定和Ｘ２检验两种方法，论证了脉动壁压概率分布服从正态分布规律。研究表明，采用峰凸系数，偏态系数判定脉动壁压的概率分布的方法有一定的局限性。 In this paper, the central and non-dimensional treatment of the fluctuating wall pressure of aerated distributary piers head is calculated by using the heap sorting method and the best interval division method proposed in this paper. Through the empirical probability density, the distribution function and the standard probability distribution According to Gliwinger theorem and X2 test, it is proved that the probability distribution of pulsating wall pressure obeys the normal distribution law. The research shows that the method of determining the probability distribution of fluctuating wall pressure by using the peak-convex coefficient and the skew coefficient has some limitations.
