黄土隧道衬砌结构的可靠度分析与研究
Reliable analysis and study on lining structure of tunnel in loess areas
摘要
Abstract
During the construction process of the tunnel lining structure, all sorts of reasons result in size shortage, which gives tunnel security operations a hidden danger, and the traditional security coefficient method can only test the safety of the structure design, while it can not judge the reliability of lining structure after the construction. This paper also noted that the stratigraphic characteristics of different regions greatly differ from each other, so for the loess tunnel and the tunnel of the other strata, the reliability research may not be the same. Therefore, this paper offers the geological radar detection as the means, from real thickness of the lining, applies probability and statistics knowledge for operation of loess tunnel lining structure reliability to make evaluation, and at the same time, this paper puts forward an ided of reducing the construction cost, by reducing the thickness on condition that the necessary structure reliability ensured.关键词
