Abstract : in order 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 tunnel excavation are obtained by the near - 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 文摘:采用近景攝影的方法,從隧道開挖毛洞中獲取圍巖超欠挖數(shù)據(jù),通過數(shù)理統(tǒng)計(jì)的方法,分析各類圍巖超欠挖的數(shù)字特征及概率分布,同時(shí)得出各類圍巖超欠挖在隧道斷面不同部位的分布規(guī)律,為隧道結(jié)構(gòu)的可靠度研究提供可靠參數(shù),也為隧道工程質(zhì)量控制提供基準(zhǔn)
