Paper Title:
Deformation Analysis of Jiagar Twin-Bore Tunnel in Tibet
  Abstract

Twin-bore tunnel is the better and useful structure form of wide span under complex conditions, and the Jiagar Tunnel is the Twin-bore tunnel of the expressway from Lhasa City to Gonggar International Airport. In the paper, we studied the deformation characteristic of the tunnel during two construction scheme, the sequential and whole excavation, by the numerical simulation of FLAC3D code. We obtained that the key points deformation characteristic was similar, the obvious part of the x-displacement is the joint of the tunnel roof and the side wall and the y-displacement is the midpoint of the tunnel floor. And the sequential excavation is better than whole excavation.
