| Abstract: | Aiming at Shenyang metro under construction,analysis on the influence of layout of small pipes for advance grouting on metro tunnel excavation was conducted.Different layout options for small pipes in radial directions were simulated,and based on the comprehensive comparison of surrounding rock stresses and displacements on monitoring points of the tunnel,the rational layout was acquired.This may be of help to similar tunnel projects. |
