Abstract
To make a large area of dredger fill silt surface layer form working face and subsequent construction problems, the project conducts the bamboo network reinforcement in the silt surface layer. It makes the surface layer bearing capacity to meet the construction requirement of deep processing. Based on Shantou Municipal Road Embankment Treatment Engineering and the project, the bamboo network reinforcement technology to reinforce the dredger fill super soft soil surface layer is used. The results show that the bearing capacity of hydraulic fill super soft soil surface layer is 32.6 kPa after 3 months treatment. The surface layer bearing capacity after 3 months treatment improved 323% than the early treatment and increased 695% than no processing. The results indicate that the reinforcement effect is outstanding and provide the basis for drafting the dredger fill super soft soil surface layer treatment plan.

Summary
With development of the hydraulic fill technology, the land reclamation will become the main means, which solves the land need of coastal cities. The surface pretreatment bamboo network technology [1]-[4] is a surface layer pretreatment technology that is based on the raft technology, which inserts the vertical bamboo in the silt and makes the bamboo network into the frame bamboo network structure. Because this technique makes the bamboo raft become three-dimensional framework, the bamboo network tends to stabilize in the plane. The paper consults the Shantou Municipal Road Embankment Treatment Engineering and uses the bamboo network surface layer reinforcement technology to reinforce the dredger fill super soft soil surface layer
