abstract = {Based on actual construction projects, compression tests were conducted on structural soft soil in four counties and districts of Fuzhou. From the perspective of engineering practice, the normalized compression curve model proposed by Burland was revised, and a double logarithmic model was also proposed as a practical model for comprehensive evaluation of the structural properties of soft soil in Fuzhou. The research results indicate that the soil in Fuzhou region has strong structural properties, and in engineering practice, empirical formulas from other regions cannot be simply applied. This paper proposes a modified normalized compression curve model that can intuitively reflect the compression behavior of soil in Fuzhou area, which is very convenient to apply in engineering practice. The double logarithmic method proposed in this article can conveniently determine the yield stress of structural soft soil, and combining the slope of the straight line in the yield stage and transition zone stage can provide reference for checking the bearing capacity and deformation calculation of foundation in engineering practice.}
