| Abstract: | In ordr to provide the reasonable parameters in the reliability analysis of tunnel structure and the criterion in the quality control of tunnel engineering, in this paper, the over-under-excavated values of the real-state outline of tunnl excavation are obtained by the nera-field photographic method. By using mathematical statistic method, the figure features and probability distributions of the over-under-excavated values of the surrounding rock,including deferent positions of same cross section, are analyzed. |
