Abstract: According to the complete deformation of transportation tunnel, widespread failure of supporting construction, and the serious deformation, we determine that roadway surrounding rock belongs to expansion-fracture highly-jointed soft rock through the analysis of failure features and the deformation mechanism; what's more, based on the original supporting scheme, we propose two schemes, that is, long anchor cable + anchor net spray (scheme 1) and multilevel roof controlling by long and short anchor cable + anchor net spray (scheme 2), and we simulate their effects by means of FLAC^3D software; furthermore, the practice shows that the latter scheme makes a great difference to improve the stress state of tunnel surrounding rock and effectively retard the harmful deformation of tunnel. To be specific, compared with the original supporting scheme, the biggest amount of roof subsidence becomes 96.87 mm, two-side displacement is 111.1 mm and floor-heave quantity is 112.7 mm, respectively 22.4%, 17.63% and 32.18% of the original supporting scheme. It improves the stress state of roadway surrounding rock, the effective control of harmful deformation of roadway.
