Geotechnical properties of sediments from the Fujian-Zhejiang coastal area and their cause brief analysis

  • Received Date: 2009-06-27
  • A comprehensively physicomechanica1 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.
