Particle size distribution(PSD)is a fundamental physical property that significantly influences the engi-neering properties of soil.Various methods exist for measuring PSD in marine sediments;however,the consistency and correlation between different measurement results need to be discussed.We deduced the relationship between sedimentation analysis method and laser diffraction method,and proposed a conversion method based on their tes-ting principles.By employing the two methods,we analyzed the PSD of deep-sea sediment samples from the South China Sea and the Shenhu Sea area,and then converted the PSD obtained from laser diffraction method according to the conversion relationship.Results reveal that the difference between sedimentation analysis method and laser diffraction method mainly lies in the content of clay and silt particles.After the conversion,the measured percenta-ges of clay and silt particles align well between the two methods,validating the reliability of the proposed conversion.
