试论掺气分流墩墩头脉动壁压概率分布规律

Research on the Probobility of the Fluctuating Wall Pressure Produced by Aerated - Flow - Splitting Pier

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。

Applying with probability therory and X2 check method, this paper has proved the fluctuating wall pressure of the pier-body produced by aeratedflow-splitting pier to be with normal probability distribution.
