Analysis of distribution characteristics of soil nailing stress

In this paper an analysis results with three-dimensional numerical simulation is made on a foundation pit in Beijing in order to study the distribution of soil nail forces. Though this we draw a conclusion that the soil nail rod bears a spindle distribution which bears bigger force in central section and smaller forces on both ends. Besides,each row of soil nail force has a great difference that the force is bigger within the scope of a third depth of the central section of the foundation pit while smaller on both sides.
