Stress Analysis about Flat Ratio and Surrounding Rock of Large Section Highway Tunnel

Abstract:

By utilizing finite element software MIDAS-GTS, layer structure model is established and the force situation of large section tunnel under the combination of three sets of surrounding rock and three sets of flat ratio is analyzed. Through comparing axial force of anchor, axial force and bending moment of shotcrete and displacement of the lining, the optimal flat ratio is selected. Results can provide reference for the design of the large section highway tunnel.
