Based on the direct analysis of two dimensional finite element method of deep excavation, author makes back analysis of soil parameters in deep excavation considering soil disturbance. According to the uncertainty of deep excavation, the best optimization for back analysis and prediction for displacement of excavation are build up based on back analysis model. The program of back analysis has been drawn up.
