Abstract：Owing to the complexity of stress characteristic and space effect of tunnel connection，the problem of tunnel connection is always the hotspot with difficulty in underground engineering. Aimed at the present situation that there is few theoretical and experimental achievement for long-span branch tunnel，the stress characteristic of tunnel connection with long span is simulated by using FEM，and the regularities of distribution of displacement，stress and internal force are studied.
