摘　　要：深水海底管道铺设中,长周期涌浪频率与深水铺管船振动频率接近,易引发结构物与海上涌浪的耦合共振,导致工程风险甚至引起海上事故。文章提出了一种基于双目立体视觉原理的海上长周期涌浪谱峰周期现场测试方法,并针对我国某海域的深水长周期涌浪进行了海上测试,为铺管海域涌浪谱峰周期监测提供了新的方法与借鉴。The approximation for long period swell frequency to natural vibration frequency of deep water subsea pipeline laying vessel can easily lead to coupling resonance,which lead to engineering risks and marine accidents.In this paper,a new testing method for spectrum peak period of long-period swells based on binocular stereo vision has been proposed,and a deep-water long-period swell testing in a domestic sea area has been completed,which provides engineering reference for spectrum peak period monitoring of subsea pipeline swell.
