摘要

摘要: 基于在南黄海中部获得的海底沉积物原位声速数据,分析讨论了原位声速与密度、含水量、孔隙比、孔隙度等沉积物物理性质参数的相关关系。通过回归分析建立了海底沉积物原位声速预测方程。结果表明,原位声速与上述物理参数之间具有良好的相关性,相关系数r均大于0.93。对比分析了原位声速预测方程与甲板声速预测方程的差异,两者最小相差15.8 m/s,最大相差31.3 m/s,平均差值约为22.6 m/s。将原位声速预测方程与其他研究者建立的声速预测方程进行了对比,结果表明不同声速预测方程存在明显差异,初步分析了存在差异的原因。

Abstract: Based on the sound speeds of seafloor sediments measured in-situ in the middle area of the southern Huanghai Sea, the correlations between the in-situ sound speeds and the physical parameters of seafloor sediments such as density, moisture content, porosity ratio and percent porosity are analyzed.The predicting equations of the in-situ sound speeds are established by means of a regression analysis.The result shows that there are good correlations between the in-situ sound speeds and the physical parameters with the coefficients r>0.95.The comparison between the predicting equations of the in situ sound speeds and those established based on the sound speeds measured in laboratory on board indicates that their average deviation is 22.6 m/s with a minimum of 15.8 m/s and a maximum of 31.3 m/s.The comparison between the predicting equations of the in-situ sound speeds and those developed by other authors demonstrates a distinct difference among the different predicting equations of sound speeds, and the reasons are discussed
