In order to analyze the stress-strain characteristics of loess tunnel and slope under the disturbance of loess tunnel construction,this paper takes the loess tunnel construction of G85 Yinkun Expressway as the background,adopts three-dimensional numerical analysis method to simulate the working condition of tunnel entrance excavation on the basis of fully investigating tunnel survey and design data,and puts forward reasonable suggestions for tunnel entrance support based on the analysis of calculation parameters to guide the safe construction of tunnel.
