本文初步建立了浅层声波勘探K参数方程,并用该方程计算了舟山海区浅层沉积物的平均声衰减系数,依此把调查区海底沉积物划分为:Ⅰ.低声衰减区;Ⅱ.中声衰减区;Ⅲ.高声衰减区。本文还讨论了这3个区的浅层沉积物分层结构及其地质意义。
In this paper, the K parameter equation of shallow sonic exploration was established and the average sound attenuation coefficient of shallow sediment in Zhoushan sea area was calculated by using this equation. The submarine sediments in the survey area are divided into: Ⅰ. Low sound attenuation zone; Ⅱ. Medium Sound attenuation zone; Ⅲ. High attenuation zone. This article also discusses the shallow sediment stratification structure and geological significance of these three areas.
