Abstract: | The general soil nailing support is not suited to the miscellaneous fill,unstable silt and mucky soils.Therefore, composite soil-nailing wall is proposed to solve the problem in the area.Composite soil-nailing wall was applied on the pit supporting of the construction,which gained excellent achievements.This article introduces the craft and mechanism of composite soil-nailing wall according to the engineering practice.And though the data got from the engineering practice,we can get the conclusion that the composite soil-nailing wall is an effective support method. |
