摘要
基于1987年和1988年夏季在古镇口港直立堤前的实测资料,对波浪和波压力连续记录进行了统计分析和谱估计,研究了在堤前海浪不发生破碎条件下,堤前波浪和堤面不同高程上压力波的波面高度概率分布、堤前波浪波高和周期与波压力幅度和周期的概率分布特征、入射波行近提前过程中的谱变化及堤面不同高程上压力谱的变化特征。主要结果总结在本文最后一节。
On the basis of data measured in Guzhenkou harbor in summer in 1987 and 1988,the statistical analysis and the spectral estimation on waves and its pressures in front of the breakwater were carried out.Without any wave breaking,the studies on the profile eleva-tion probability distribution for both the waves in front of the breakwater and the pressure fluctuations at different depths of the breakwater,the probability distribution characteristics of the wave heights and periods and the ranges of pressure fluctuation or periods for the wave pressure,the spectral variation during the incident waves propagating to the breakwater,as well as the variation characteristics of pressure spectra at different depth of the breakwater were made.The main results were summarized in the last section of this paper.
