论文摘要

液体波研究表明,在某些建设性干扰条件下,可以在特定点产生异常的大小波。这种类型的波浪在文献中很久以前描述了1995年被称为“ Draupner Wave”。这是第一个高十米高的流氓浪潮,可通过测量仪器检测到,该仪器发生在挪威沿海北海的Draupner平台上。对于大陆沉积盆地中非常柔软和厚的土壤,水分含量很高,低剪切波速度和波浪弹跳对盆地边缘的影响,人们可以质疑这种类型的怪胎波在表面地震波中可能未被发现的这种怪胎波的理论存在。这种简短的交流表明了重力和地震波之间的类比的最新观察以及局限性。

Liquid wave studies have shown that under certain constructive interference conditions, an abnormal size wave could be generated at a specific point. This type of wave, described long ago in the literature, was named 'Draupner Wave' in 1995. It was the first rogue wave, more than ten meters high, to be detected by a measuring instrument, occurring at the Draupner platform in the North Sea off the coast of Norway. For very soft and thick soils in continental sedimentary basin, with high water content, low shear wave velocity and wave bouncing effects on the edges of the basin, one can question the theoretical existence of such a type of freak waves that may have come unnoticed amongst surface seismic waves. This short communication presents recent observations and the conditions and limits of the analogy between gravity and seismic waves.
