Data Simulation Analysis of Support Principle to Soil Nail by FLAC3D

With the example of construction to establish analysis modle of soil nail support stability,and choose the FLAC3D to do the data stimulation.Changing rules of stress field and strain field in non-support excavation and support excavation are revealed by the stimulation.To further research the soil nail support principle and support capability.Data stimulation conclusion can supply the theory and reference designing data for support design and construction.
