Abstract
Finite element analysis of tunnel construction in urban area is given. Soil material model parameters determination is considered. 3d finite element analysis of tunnel development is carried out. Variation of settlements and settlement troughs according to face and radial shield pressure and initial stress state are shown. Comparison of numerical modeling results and results of in-situ settlements measurement is done.
