| Abstract: | Based on the viewpoint of the semi- analytical numorical method, this paper presents a construction method of semi-analytical displacement functions and the numerical sAnulation process for the construction of parallel tunnels,using time-changing mechanics and viscoplasticity theory. The rcsearch of this paper provides a theoretical basis for fast and safe construction of parallel subway tunnels in urban condition. The construction case of two shields driving in the same direction is slinulated with the analytical and numerical method proposed in this paper. |
