Study on Harbin Metro Shield Tunnel Segment and the Deformation of Tunnel Rock

Abstract:

Deformation of segment and rock is one difficult question of the subway design. When building the calculation model of the liner we mainly think about the effect on the liner of the joint and the resistance force of the earth. In this paper the joint of the model of the used model is improved and the inner force formulas for the new model are derived. At last, the derived formulas and the existing formulas are validated by Harbin Metro Line 1. According to the research result, we can know the formulas derived in the paper are credible and they have academic practical meaning for design and construction of the subway liner.
