本文首先概述了黄、渤海的风和浪基本情况,根据国家海洋局、渤海沿岸8个典型台站26～30年的波浪实测资料,进行了波浪年极值统计分析,选用三参数Pearson—Ⅲ型分布及四参数指数Γ分布两种线型,并用最小二乘法与优选法相结合的寻优适线法(FIT)对分布参敬进行估计,从而得出黄、渤海8个典型台站不同重现期的设计波要素。研究表明四参敬指敬Γ分布比三参数Pearson—Ⅲ型分布适线的弹性更大,对经验频率的拟合精度更高。但两种分布的计算结果相差不大。本文为水利部技术开发基金项目“中国沿海风浪统计分析”第二阶段研究报告。
This paper first outlines the basic situation of the wind and waves in the Yellow Sea and the Bohai Sea. According to the observed data of waves from 8 typical stations of the State Oceanic Administration and the Bohai Sea for 26 to 30 years, the extreme value statistical analysis of the wave year is conducted. The three-parameter Pearson-Ⅲ Type distribution and four-parameter exponent Γ distribution, and the least squares method and the optimal combination of optimal fit method (FIT) to estimate the distribution of reference to obtain the yellow, the Bohai Sea, eight typical stations of different weights The current design wave elements. The research shows that the four-reference finger is more elastic than the three-parameter Pearson-Ⅲ type, and the fitting accuracy to the empirical frequency is higher. However, the results of the two distributions are not much different. This article is the second phase research report of “Statistical Analysis of Coastal Wind and Waves in China” project of the Ministry of Water Resources Technology Development Fund.
