摘要： 采用近景摄影的方法,从隧道开挖毛洞中获取围岩超欠招数据,通过数理统计的方法,分析各类围岩超欠控的数字特征及概率分布,同时得出各类围岩超欠挖在隧道断面不同部位的分布规律,为隧道结构的可靠度研究提供可靠参数,也为隧道工程质量控制提供基准.

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.

Key words: near-field photography, over-under-excavated values, mathematical statistic method
