极软土中地震异常波的可能性

On the possibility of seismic rogue waves in very soft soils

Stephane Brule, Stefan Enoch, Sebastien Guenneau

摘要:

液体波的研究表明,在一定的相长干涉条件下,在特定的点上可以产生异常的尺寸波。这种类型的波,很久以前在文献中描述过,在1995年被命名为“Draupner波”。这是第一个由测量仪器探测到的超过10米高的巨浪,发生在挪威海岸外的北海的Draupner平台。对于大陆沉积盆地中的非常软和厚的土壤,具有高含水量、低剪切波速度和盆地边缘的波浪反弹效应,人们可以质疑在表面地震波中可能未被注意到的这种类型的反常波的理论存在。这篇简短的通讯介绍了最近的观测结果以及重力波和地震波之间类比的条件和限制。

英文摘要:

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.
