摘　　要：海上以护筒为依托搭设满铺钻孔平台,进行嵌岩灌注桩施工的工艺应用较广泛,但若施工条件发生变化,则其施工工艺也将随之变化。结合福建大唐宁德电厂煤码头的施工条件,提出"振动锤沉桩—原平台延伸分2层平连稳桩—满铺平台上钻机成孔"施工工艺,成功解决了海上浅覆盖层灌注型嵌岩桩钻孔平台搭设问题,使该工程工期提前,获得良好效益。The method of rock-socketed cast-in-place piles with the support of sleeve applied on the full- paving drilling platform is the commom one widly used in marine construction. The construction technology will vary with the change of the construction condition. According to the construction condition of the Coal Wharf in Datang Ningde Power Plant in Fujian province, the technology of ＂sinking pile by vibration hammer,extending the original platform to flat stable pile and drilling hole on the full-paving platform＂ is put forward. It successfully solved the drilling platform erection of cast-in-place rock-socketed pile on the maritime shallow coverage layer. The construction period is ahead of schedule and it make a great benefits.
