Abstract：Mine tunneling and shield tunneling methods are often built with small intervals when the auxiliary lines approaching to a subway station.The cross sections caused by mine tunneling are often extensive and va-rious.When shield tunnel is being built, the impact of the two tunneling engineering is significant.This paper establishes a three dimensional numerical simulation of the construction process of certain tunnel construction by means of the finite element program FLAC3D .The influence of tunnel construction on wall rock is analyzed, and the laws on how the post-constructed tunnel affects the displacement and stress distribution of the pre-constructed tunnel are discovered.The conclusions of this paper are expected to be used as a reference for construction organizations and other similar engineering projects.
