THE INFORMATION CONSTRUCTION MANAGEMENT ABOUT INITIAL SUPPORT OF HIGH-SPEED RAILWAY TUNNEL IN LOESS REGION
During the process of tunnel construction, it is very necessary to insist on the information construction management and take measures. Taking the Humaling tunnel as the background, mechanical properties of its typical cross section’s surrounding loess are comprehensive researched by in-situ monitoring and FEM calculation, and then explored the mechanical rules of the initial support for high-speed railway tunnel in loess . The initial support effects can be evaluated; meanwhile several corresponding optimization measures are put forward aiming at the weaknesses of the initial support process. Based on the above, some advices and techniques are provided for the initial support in the similar loess region.
