Abstract:: In high earthquake intensity area,strong seismic motion may cause the ruin of highway tunnel,especially the entrance of tunnel,the weakest part of the tunnel.Based on the soil-structure interaction model,we used FLAC3D soft and numerical analysis method to analyze the dynamic time-response of tunnel entrance.The analysis shows that the arch and wall foot are lied in unfavorable locations,need reinforcing steel bar in seismic design,and the function of wall rock should be paid more attention to in construction,since it can reduce the damage of structure when it acts with structure together.
