Application of construction technology of steel cement-soil wall with uniform hickness in rock-socketed deep excavations in complex soil strata

Based on the application of construction technology of steel cement-soil wall with uniform thickness (TRD method) in Greenland Central Plaza in Nanchang, the TRD method is introduced related to its application in rock-socketed composite retaining structures in complex soil strata. It is shown that the TRD method has advantages of wide adaptation to soil strata, fully mixing and good water-resisting properties and so on. As a green construction method, the TRD method has obtained remarkable comprehensive economic and social benefits. It may provide valuable reference for similar projects in the future.
