| Abstract: | The sources of all sort of error that affect the accuracy of measuring construction gauge of tunnel with mechanical convergence meter, were analysed and argufied strictly by appling the variance theory in this paper. The result indicates that the measurement standard deviation of base line is inconsiderable to convergence value of every measuring point. |

| Keywords: | convergence of tunnel construction gauge absolute convergence value relation convergence value standard deviation |
