| Abstract: | In this paper,shield tunnel was regarded as an uniform beam placed on elastic ground in lognitudinal direction.With the help of this model,the authors analyzed stress distribution in tunnel structure and crack development of joint induced by uneven load and settlement along the tunnel.At the end of this paper,based on a case study of tunnel,the tunnel stress is analyzed. |

| Keywords: | Shield tunnel Equivalent uniform beam Uneven settlement Mechanical analysis |
