An experimental study on soil stabilization using soil nails

Abstract

Soil nailing generally consists of the enduring reinforcement of the existing ground by planting or inagurating closely spaced steel bars (i.e. nails). In soil nailing generally the construction proceeds from top to bottom.To provide continuity shotcreting or concreting is also done on the excavation face. The performance of the structure in a soil nailed wall is generally affected by three components—the native soil,the reinforcement and the facing element.The performance of the structure is also affected by the mutual interactions of these three components. The principal of soil nailed wall is the development of friction between the compacted earth mass and reinforcing elements.The soil transfers the forces built up in the earth mass to the reinforcement by means of friction. Thus,tension is developed in reinforcement. Soil Nailing technique is generally classified broadly into two main categories: 1. In-situ soil reinforcement. 2. Remoulded soil reinforcement.
