Abstract

Long-term settlement is a big issue which should be consider for dredger fill soft soil foundation. This paper analyzed the long-term settlement of a road engineering located at Tianjin Nanjiang Port. The long-term settlement was calculated based on “Code for Foundation of Port Engineering”, and the predicted result is compared with the in-site monitoring data. The comparison results show that the long-term settlement calculation results based on code should be modified before using for settlement prediction. The modify factor is 1.1 to 1.3 for Tianjin area, and the factor should rises to 1.5 when the value of preloading is small and the foundation stiffness is small.
