| Abstract: | In this paper,an approach for predicting the deformation of the supporting structure of foundation pit is developed by analyzing the measured data at site and reverse analyzing m value. A prediction of the deformation of supporting structure can be made through finite element computation, and excavation of foundation pit may be regulated according to the prediction result for effective and safe construction. |
