根据闽浙沿岸沉积物的实验室分析资料,从物理性质和力学特征对海底沉积物的综合工程地质特征进行了研究,结果发现,本区沉积物以淤泥和淤泥质黏土为主,含少量细砂、粉砂、黏土和粉质黏土等,总的表现为含水率高、孔隙比大、压缩性强、塑性大和强度低.从微观结构、物质来源、物质成分、水动力条件等方面对沉积物的工程特性进行了成因分析,这些因素是造成本区沉积物工程性质不良的主要原因.

A comprehensively physicomechanical property study for the sea bottom sediments was made through the analysis of the sediment samples taken from the Fujian-Zhejiang coastal area.It is revealed that the sediment here is composed of fine sand,silt,mud,muddy clay,clay,and silty clay,of which mud and muddy clay are the main types.The sediments are characterized by high water content,high void ratio,high compressibility,high plasticity and low shear strength.Furthermore,the reasons caused the poorly geotechnical properties of the bottom sediments were analyzed from the points of microstructure,matter source and composition,hydrodynamic environment.They are the dominating factors to induce the poorly geotechnical properties of the sediment in this area.
