Abstract Based on the construction process character of deep excavation，the method of back analysis and numerical simulation of dynamic deformation during construction process is set up by semi-analytical layer elements. Thus the values of the dynamic elastic moduli of soil layers are obtained. The deformations of wall and soil ground are predicted by use of the obtained values of elastic moduli of soil layers and are in good agreement with that of in-situ test.

Key words： engineering of deep excavation semi-analytical numerical method back analysis of construction deformation prediction
