Abstract: As a newly excavation retaining structure，the constant thickness steel sement-soil wall, which was constructed by the TRD construction method, has the characteristics of extensive applicability in soil layers, high homogeneity, high reliability of mechanical behavior and waterproof, and so on. The first time, it was successfully used in the excavation project of Nanchang Greenland Center Square. The excavation area is about 14 000m², and the excavation depth is about 15.45~17.45m. Based on the project, the characteristics, application conditions, key design technology of the new excavation retaining structure were introduced.

Keywords: TRD construction method; constant thickness steel cement-soil wall; vertical mixing; waterproof wall
