摘　　要：大顶子山船闸上下游隔流堤、靠船墩均为抛石基床结构,抛石11万m3,其中水下6.7万m3。水下抛石高差难控制,抛石夯实质量不易保障,基床粗平和细平的平整度控制难度大。通过夯实试验,摸索出一整套基床整平的施工技术,解决了水下抛石基床施工质量控制等难题,并总结出一整套水下抛石基床施工技术并积累了经验。Ship Lock upstream and downstream at Dadingzishan separation levee approach channel of TGP and pier structure both are rubble-mound foundation, rubble-mound is about 110,000 m^3, of which 67,000 m^3 is underwater. Refractory elevation of Rubble-mound is very hard to be controlled underwater, and the compacted quality of rubble-mound is not to be ensured, meanwhile, the foundation roughness control is very difficult. Through the compact test ,the author explores a set of leveling the base of the construction techniques to solve the underwater construction of rubble-mound foundation quality control problems, and summarizes a set of underwater construction of rubble-mound foundation technology and accumulated experi- ence.
