Discuss on Seismic Conceptual Design of Tunnel Engineering

The authors put the seismic conceptual design which widely used in building structure into tunnel.Analyzed four main contents of seismic conceptual design in the mountain tunnel: site selection,proper weighted principle,constitution methods and space action principle.A conclusion is gained that seismic conceptual design is effective in guiding tunnel seismic design.Moreover,theoretical basis and design skills of conceptual design need to be packed,skilled designers are also one of the most important factors on seismic conceptual design oftunnel.
