漩门三期围垦工程规模大，涂面深，海堤基础采用爆炸挤淤置换法进行处理，龙口设计采用置换龙口的型式。置换龙口的形成和合龙不同于塑料排水插板等地基处理的常规龙口。针对置换龙口的设计，进行大量的龙口水力要素计算，分析、研究影响置换龙口合龙的关键因素，以确定爆炸推进控制、置换口门开挖的方式及时间，获得“置换龙口”成功合龙。

The third phase reclamation project of Xuanmen is large-scale with deep coating .The explosion sludge-extruding displacement method is adopted to deal with the seawall foundation ,and replace-gap reclamation is used to design closure gap . The formation and closure of gap replacement are different from plastic drain flapper or other conventional closure of foundation treatments .In views of closure gap replacement design , this paper made a large amount of calculation about its hydraulic elements ,and analyzed the key factors influencing closure gap replacement .Then the paper determined the way and time of explosion propulsion control and replacement entrance excavation to realise succussful closure of gap replacement .
