In the 1～3 berth project at Kemen work zone in Fuzhou port,deep soft foundation exists at the revetment of flood discharge trench,but the surface layer is covered by so many block stones that it is difficult to implement soft foundation treatment to the substratum.Aiming at this problem,the scheme of adopting the method of combing guide hole with pipe sinking gravel pile was put forward for the soft foundation treatment.This scheme successfully solved the technical problem of dealing with the underlying soft layer by penetrating hard layer,and obtained a good effect.This designing scheme and construction method can provide a reference for the design and construction of similar projects.
