Study on Deformation Law and Mechanical Mechanical Analysis of Large Cross Section Bias Loess Tunnel
To ensure the safety of tunnel construction,the deformation law and mechanical characteristics of large cross section bias loess tunnel construction were analyzed and summarized using on-site measurement methods.The results show that during the construction process of the three step method for a large section biased loess tunnel,the tunnel deformation roughly went through three stages of change:rapid deformation in the early excavation stage,continuous growth in the middle excavation stage,and slow growth after excavation completion.The stress distribution of the support structure in the large section of the biased loess tunnel is uneven along the tunnel cross-section space,and the pressure values at the arch crown and arch waist are relatively high.
