摘要
对于缺乏长期波浪观测资料的新建港址,利用风况观测资料推算风成浪,是确定设计波浪的简便方法。选取宁波-舟山海域两处工程实例,分别运用国内主要浅水风浪推算公式——规范法与莆田法,对海湾水域与岛屿环抱水域两种典型海域进行不同重现期设计浅水风浪要素的推算。通过对风区长度、风区平均水深以及设计风速等主要变量的工况组合,归纳两种方法的计算结果差异性与适用性,结论可供工程设计参考。
It is a convenient method to estimate design wave parameters utilizing the wind observation for wind wave factors in case there is no observed hydrologic data on the engineering site. Through two typical project cases in Ningbo-Zhoushan sea area, this paper calculates the wind wave factors by two principal means, i. e. national code method and Putian empirical method, and evaluates and compares the suitability and effectiveness of two formulas through combining three primary parameters into conditions (including fetch length, average depth and design wind speed), which can he used for reference in the engineering design.
