日照港工程波浪计算分析及其应用
|
摘要
本文在对日照港多年波浪要素分析的基础上,采用考虑波浪折射、绕射、反射以及波能损耗等多种物理过程的波浪数学模型研究日照港波浪要素,综合计算两种水位、三个波向两年一遇组合情况下日照港码头扩建前后的港池内波浪要素,对港池泊稳条件进行分析.计算结果表明:日照港西港区扩建工程对港池波浪影响不大,而防波堤的建设对港池内波浪要素影响很大,使得港池内波浪普遍变的平坦,有效的掩护了港池区域,防浪效果明显,符合港区内的泊稳条件.
Based on analysis of Rizhao harbor year-wave-data,the wave characteristic of harbor basin will be studied by using a wave mathematical model considering wave refraction,diffraction,reflection,wave energy loss and other physical processes. The wave elements in the harbor basin before and after the extension of Rizhao harbor are calculated by combining the two water levels and three wave directions,and the berthing stability condition of the harbor basin is analyzed. The results show that the west port expansion project of Rizhao harbor has little effect on the wave of harbor basin,and the construction of breakwater has a great influence on the wave characteristic in the harbor basin,which makes the wave become flat effectively,protects the barbor pool,and conforms to the mooring stability condition in the port area.
