  • The dredger fill is formed under the hydraulic filling,which consists of fine particles and has a poor consolidation capability.Its natural sedimentation and consolidation after dredger filling is a very slow process,and only when the surface duricrust has formed,the ground improvement can be started.So it is urgently necessary to accelerate the consolidation process,and transform the dredged mud into a solid ground which has a certain bearing capacity.Laboratory model tests were carried out to simulate the effect of consolidation agent.Lime and cement were chosen as the consolidation agents to be added into the dredger fill to accelerate the consolidation process respectively.The solidifying mechanism and consolidation performance of the two materials have been studied carefully.The reason for their different consolidation behavior is tentatively concluded,and the consolidation mechanism is correspondingly put forward.A more economical and feasible method for consolidating foundation of dredger fill has been provided in this paper.
