Application of the Soil Nailing Wall on Foundation Engineering

The soil nailing wall is a kind of technology for supporting and strengthening the in-situ soil. The nails are integrated with the soil around tightly, so that they can form into a type of composite soil, relying on the frictional force of contact surface. Based on the analysis of the constructional scheme of the national stadium, the key factors for controlling the quality of the construction were found. The quality system during the project should be managed strictly. And the diameter, length and strength of the anchorage ought to be executed exactly. This scheme provided, reasons for the national stadium's soil nailing wall's safety and quality assurance.
