摘　　要：大型潟湖港区往往通过狭长的运河航道与外海相连,运河内面临外海波浪、涨落潮流和船舶航行的多重影响,显著的波流耦合作用以及船舶螺旋桨射流冲刷给运河岸坡的护底防护提出了较高的要求。为了解决这种复杂水力环境下护底保护问题,通过对国际通用规范中相关计算理论的研究,总结提出了一套适宜的计算方法,便于工程人员更好地运用国际规范解决相关问题,同时可为国内规范的修编提供参考、助力中国规范与国际接轨。Large lagoon port areas are often connected to seas through narrow but long canal channels,and canals are confronted with multiple influences brought by offshore waves,ebb and flow of tides,and ship navigation.The significant wave-current coupling effect and the erosion caused by the ship propeller jet put forward high requirements for the bottom protection of canal bank slopes.In order to solve the bottom protection problem under this kind of complex hydraulic environment,this paper studies relevant calculation theories in the international standards and proposes a suitable calculation method,which can help engineers make better use of international standards to solve related issues.At the same time,the paper can provide a reference for revising Chinese norms and help them to be in line with international standards.
