Abstract Because of the influence of karst，the construction mechanics response of highway tunnel in karst differs from that of common tunnel. Through large conformable model testing and FEM，the influence of karst cave magnitude and position on construction mechanics response is studied，and some distribution rules of displacement field and plastic field of tunnel in karst are summarized.

Key words： tunneling engineering karst highway tunnel mechanics response model testing numerical simulation
