摘　　要：南京长江三桥北引桥水中墩部分承台采用轻型井点降水法施工,效果良好,极大地降低了施工成本,减少了机械设备的投入,确保了水中墩及时出水。The light well-point dewatering method is applied to construction of some of the pile caps of the north approach span in-water piers of the 3rd Nanjing Changjiang River Bridge. The method herewith works quite efficiently, greatly reduces construction cost, minimizes input of construction machinery and equipment, and consequently ensures the piers to be built above water level on schedule.
