Using the tunnel analysis method of Tokyo Bay of Japan, the calculation model of tunnel analysis that is suitable for this subject is put forward. That is to say, the equivalent mass-spring system is used to replace the foundation slice, and the beam is replaced by the beam capable of withstanding shear, bending moment and axial force. The numerical simulation shows that the axial force, angular displacement and shear force at the joint between the tunnel and the shaft are large.If the overall design permits, it is suggested that the length of each tunnel should not be too different, so as to reduce the relative power of tunnel joints under seismic wave Displacement and internal force.
