Abstract：Models for elastic，flexible and rigid joints were established. Considering the interaction between structure and soil，failure mechanism and influential factors of segments and joints at the junction of shield tunnel and shaft were studied under different working conditions based on cross-river tunnel at Weisan Road in Nanjing. The results show that segments and joints bear large internal forces and small displacements using rigid joints，while flexible joints result in smaller internal forces and larger relative displacements. The corresponding response of elastic joints is between those of flexible joints and rigid joints. The mechanical parameters of soil and slip between contact faces significantly influence the seismic response of segments and joints. The conclusions are in good agreement with seismic damage data，which can provide references for seismic design of similar projects.
