摘　　要：针对钱塘江河口涌潮观测站(点)工程——盐官站水下桩基承台的施工现状,选择了施工速度快、较为经济的整体定型钢模板围堰施工方案,并对围堰结构进行了涌潮、静水、混凝土浇筑等工况下的数值模拟分析,认为在工程实施过程中要注意钢模试吊、钢模安装固定、潮水预警、抽水及注水作业等.据此提出了一种可应用于强涌潮区、较为经济的水下桩基承台施工方法.The construction of tide observation station of the Qiantang River estuary and the underwater pile cap in Yanguan Station is introduced,and the more speedy and economical cofferdam scheme for the whole stereotyped steel formwork is also adopted.The numerical simulation analysis of cofferdam structure under the condition of surging tide,still water and concrete pouring is made.The attention points in the construction process are summarized,such as steel formwork installment,tide early warming,water pumping and operation,accordingly,a kind of more economical underwater pile cap construction method is put forward,which can be applied in strong tidal areas.
