黏土地基上建设大型重力式码头的沉降控制

Sedimentation control for construction of large-scale gravity wharf on clay ground

曹妃甸通用码头工程为曹妃甸地区首座沉箱重力式码头,码头的沉降控制还未有可供参考的数据,在黏土地基上建设10万吨级的大型重力式码头的重点在于对沉降的控制。针对曹妃甸港区的地质情况,从设计方面对基床、沉箱、回填料均采取了优化措施,从施工方面对施工质量严格控制,并严格按照监测结果指导施工,从而成功控制了码头沉降,实际监测结果也证实了措施的有效性。

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.
