%X An approach for predicting the displacement of the retaining structure of foundation pit is proposed based on in-situ data,optimum back analysis and elastic finite element method. With the monitoring information of displacement in the process of deep excavation,the optimum back analysis is used to calculate the properties of soils and retaining structure,which are then applied to predict the displacement of the retaining structure in the next stage. The back analysis is repeated in subsequent stages until the end of excavation. The results of back analysis provide guidance on design and construction of deep excavation and assessment on the security of excavation operation.
