Abstract: This paper presents a case history of preloading surcharge method used in the soil improvement of soft soils underneath a proposed large container yard in Jintang Island, Zhoushan City of Zhejiang Province. The design and construction aspect of the preloading surcharge method. The geotechnical instrumentation program included surface as well as layer ground settlement, layered lateral deflection and pore pressure dissipation. The vane shear test, standard penetration test and laboratory testing were used in the evaluation of the surcharging results. Lessons learned during the construction are also presented in the paper.
