Study on three dimension seismic analysis of the underground regional tunnel
2013
Under the frame work of soil-structure dynamic interaction theories and viscous artificial boundary element,a finite element model of soil-structure interaction with the help of ABAQUS software has established.Seismic responses of subway tunnel’s lining structure and station structure are analyzed,including factors which influent it.Three-dimensional subway interval tunnel finite element model is established with ABAQUS software.The interval tunnel seismic responses are analyzed under different seismic waves,including SV waves and P waves.The seismic response of interval tunnels are studied with different lining thickness,different lining materials,different geologic conditions and different directions of seismic waves.The corresponding influence disciplinarians are obtained.
