Researches on bracing system of foundation pit using simplified space analytical method

Considering earth pressure and bracing force changing with displacement under the consideration of interaction among soil retaining structure bracing system,in this paper,a simplified bracing system space analytical method is proposed.Programs for calculating have been edited.The method can be used to analyze the inner forces and deformation in retaining structure and bracing system of the foundation pit with the same or different excavation depth and different soil layer,ect.
