摘要:
运营阶段的隧道,随着时间流失其结构是否依然安全可靠?这一直以来都受到了人们关注.而传统的安全系数法在这个阶段已不能发挥它的作用,那么对于施工后衬砌结构可靠性的检验方法也只能运用数理统计知识了.但就其在现役隧道衬砌结构可靠性方面的应用成果来说,目前还比较少,这主要归咎于地下结构有太多的不确定性.而且黄土隧道与其他地层的隧道在结构可靠性的研究成果存在着一定的不通用性.因此,找到一个合理评价黄土隧道衬砌结构可靠性的方法是现阶段最主要的任务之一.为此,本研究提出以SIR3000地质雷达探测为手段,从实际衬砌厚度入手,应用概率统计知识对运营中的黄土隧道衬砌结构可靠性做出评价,同时,提出在保证必要的结构可靠概率条件下,通过减少施工时的衬砌厚度来降低施工成本的思路
Abstract:
As a used tunnel, is its structure safe and reliable with time passing by? This has been paid close attention to by the people. In view of the fact that the method of the traditional safety coefficient already can′t play a role, the inspection method on the reliability of the lining structure can only use the knowledge of mathematical statistics. But it is more less in term of the application results about the reliability of lining structure at present, this is blamed on the underground structure since it has too much uncertainty. And the loess tunnel has certainly not been universal in the research results of the structure reliability with the tunnel of the other strata. So at the present stage, one of the main tasks is to find a reasonable evaluation method of loess tunnel lining structure’s reliability. Therefore, this paper offers SIR-3000 geological radar detection as the means, from real thickness of the lining, and applies probability and statistics knowledge for operation of loess tunnel lining structure reliability to make evaluation. At the same time, this paper puts forward an idea about reducing the construction cost by reducing the thickness to in the condition of ensuring the reliability necessary for the structure
