摘    要:根据南黄海中部海底沉积物柱状样的实验室土工试验测试结果,分析沉积物的物理特征,并通过实验室方法获得沉积物压缩波速,探讨物理参数与压缩波速的相关关系,得到经验公式。结果表明:该区域沉积物以淤泥和淤泥质黏土为主,具有含水率高、孔隙比大、塑限高等特征;物理参数与压缩波速之间有较好的相关关系,密度、孔隙比、含水率、塑限、液限及塑性指数与压缩波速的相关性最明显,其中,密度与压缩波速成正比相关关系,而孔隙比、含水率、塑限、液限和塑性指数与压缩波速成反比相关关系;以沉积物天然密度和塑性指数为自变量的双变量回归分析方程能更好地表达沉积物物理特性与压缩波速的相关关系。

关 键 词:南黄海中部  海底沉积物  物理参数  压缩波速

Abstract:A physical property study for the sea bottom sediments was made through the analysis of the column sediment samples taken from the South Yellow Sea,in China Sea,and the compression wave velocity were obtained by laboratory test.The geotechnical test results show that the mud and muddy clay are the main sediment types.The sediments are characterized by high water content,high void ratio and high plasticity.By studying the relationship of physical properties and the compression wave velocity,the compression w...
Keywords:central part of the South Yellow Sea  sea bottom sediment  physical properties  acoustic characteristics
