According to the engineering characteristics the project is divided into four typieal operating conditions. Horizontal displacement of supporting pile is measured in the end of each condition.Moreover supporting pile deformation rules are analyzed during excavation.Through the establishment of three-dimensional model the supporting pile deformation is simulated and the results are pared with experimental results.Eventually the deformation of deep foundation excavation support and influence sphere of earth excavation are gained. Key words:subwa...
