Tunnel Collapse Treatment Technique Research in Xinjiang Tianshan High-Altitude, Low-Temperature Mountain
Based on YuXiMoLeGai tunnel in G217 Cholma to the Nalati highway, aiming at the outlet section of K723+911~K723+919 collapse, through model experiment and numerical calculation combined with on-site measurement, the article studies tunnel collapse treatment technique and technical effect in xinjiang tianshan mountains in the geological conditions of high altitude, low temperature, crushing of rock mass and rock rich in water. The results show that after the CRD method, expanding the scope of the grouting construction, increasing the number of small duct grouting lock foot, strengthening methods of supporting parameters are adopted, vault subsidence deformation rate is 0.4-1.5 mm/d, peripheral convergence deformation rate is 0.5-2.2 mm/d, stress the most unfavorable right hance monthly increase in stress and strain amplitude is 3.97% and 2.35% respectively.The treatment controls the land slide body deformation and stress well.
