    • Abstract
  • In this paper,the marine sediment soft soil of Beigangchi Wharf in Tianjin Port was scanned by Computer Tomography(CT) in different load during uniaxial consolidation experiment.With the CT images,the soil characteristics during consolidation were analyzed.The results show that:with the pressure growth,the average grey value of the CT images increases gradually,which indicates that soil samples are compacted and the density increases.During consolidation,the pore-water pressure dissipation leads to the structure change in the soil,which makes different trends of CT image grey standard deviation for different kinds soil.Grey compression coefficient is introduced to evaluate the soil compressibility.According to the changes of grey compression coefficient,it is illustrated that the soft soil of Beigangchi Wharf in Tianjin Port has high compressibility.
