The relationship between displacements of the excavation contour and distance to the excavation face is obtained in the paper. The relationship allows to calculate support pressure with the account for delay of the support installation. Some calculation results of axial forces in the support are given. Calculations are made on the basis of finite-element method with three dimensional models.
Numerical modeling of cast iron lining stress and strain state of pylon deep underground station is done. Due to complex geometry of underground station, step by step excavation and lining installation numerical modeling was done in three dimensional space.
