摘　　要：针对低顶岛式斜坡堤的堤顶高程确定方法,基于国内外现有研究成果和所依托的工程实践,探讨影响低顶岛式斜坡堤的堤顶高程设计关键因素,对强浪向分散、常浪向集中的情况提出堤顶高程宜使堤后次生波与非掩护浪向设计波浪基本相当的设计理念,并结合工程案例的物理模型试验结果进行对比分析。结果表明,所提出的设计理念合理、可行,对未来类似工程的设计具有借鉴和参考意义。Aiming at the determining method for the crest elevation of low-crested sloping island breakwater,we discuss key factors affecting the design of the crest elevation of low-crested sloping island breakwater on the basis of existing research findings and the engineering practice under study.For situations where strong waves are scattered and common waves are concentrated,we propose a design concept that the crest elevation should make the secondary waves behind the breakwater and design waves of the non-protected wave direction substantially equivalent,and compare and analyze results of physical model tests in engineering cases.The results show that the proposed design concept is rational and feasible,which has reference significance for the design of similar future projects.
