摘要: A shallow buried tunnel was collapsed during construction. According to the actual situation of tunnel, different collapse consolidation schemes were put forward and corresponding three-dimensional finite difference numerical models established analyzed using FLAC3D software. Base on 3D Simulation results, a scheme determined constructed. The in-situ monitoring results vault subsidence convergence displacement consistent approximately with results. measured in line specification’s allowance show that effect reinforced concrete casing arch ahead grouting method is good. This could be referenced for similar engineering.
