摘要
波浪在珊瑚礁礁坪破碎、传播后在防波堤产生爬高,波浪爬高是决定防波堤高程、人工岛高程的重要因素。基于FLOW-3D软件,建立了珊瑚礁上防波堤波浪爬高的数值模型。通过与物理模型对比,验证了珊瑚礁上波浪传播与破碎、非破碎波在防波堤爬高数值模拟的合理性。在此基础上模拟了波浪在珊瑚礁地形上破碎与传播、防波堤的爬高,表明:随着礁坪上防波堤离礁前缘距离的增大,波浪爬高逐渐减小,在距礁前缘约一个深水波长处的防波堤爬高已显著减小。
Wave run-up occurs in embankment after propagation and breaking in coral reef.Wave run-up is an important factor to determine breakwater elevation and artificial island elevation.Based on FLOW-3D software,the numerical model of wave run-up of breakwater on coral reef is established.Compared with the physical model,the rationality of numerical simulation of wave propagation,breaking and non breaking wave climbing height in breakwater is verified.On this basis,the numerical simulation of wave breaking and propagation on the coral reef topography and the breakwater climbing height shows that with the increase of the distance between the breakwater on the reef terrace and the front edge of the reef,the wave climbing height gradually decreases,and the breakwater climbing height at about one deep water wave length from the front edge of the reef has significantly decreased.
