Abstract: Filling method for embankment is of low cost, high efficiency and speed. However, as restrictions of poor bearing capacity in soft soil ground, its application in reclamation project is much less. According to the actual condition of Wenzhou shoal, combined with the construction in east polder dike project, this paper introduced some details about hydraulic filling. Further, experience such as how to control the load and resist the comprehensive interference of wind, wave and tide by sand pipes and bags and so on were presented, and the feasibility of application of hydraulic filling in complicated conditions was verified, worthy popularization.
