Abstract: The highway normal operation is easy to be influenced for the above road surface subsidence induced by the under-traverse tunnel construction.Taking a tunnel construction channel as example,using ABAQUS to simulate the 3 Ddynamic construction process,the influence of tunnel excavation to above highway road surface subsidence is analyzed,the surface subsidence value in all stages of the excavation and supporting structure stress change rule are obtained.Numerical calculation shows that the tunnel excavation will not endanger the normal operation of above highway.
