Caofeidian general wharf is the first caisson gravity wharf of the Caofeidian area, and there isn’t any referential data for the wharf’s sedimentation control. The focal point for the construction of 100 000 DWT gravity wharf lies in the settlement control. According to the geologic condition of Caofeidian port area, we took a series of measures including optimization of design for the foundation bed, caisson and backfilling materials, strict control for the construction quality and guidance to the construction according to the monitoring results, and the sedimentation was controlled effectively therefore.
