Numerical Simulation Analysis on a Construction Method of Ultra-Closing Over-Cross Transportation Tunnels

Article Preview

Abstract:

By numerical simulation approach, this paper analyzed a new construction method for over-cross tunnel. In this method one concrete framework and two connecting walls were used in the intersection zone to meet the requirement of ultra-close distance between the two tunnels: the lining of upper tunnel rode through on the lower one’s via two connecting walls. This paper conducted a series of study on the mechanical behavior of rocks and structures during the construction period. The stability of the structure and the feasibility of construction method were evaluated.
