摘要:
隧道病害严重影响了隧道结构的稳定性、可靠性及安全性，严重影响隧道的正常使用，病害严重时甚至可引发安全事故．基于隧道信息检测及反分析方法，提出采用一种隧道病害快速诊断及其防治技术，并以重庆某顶压隧道为工程依托进行应用，得出以下结论：1） 隧道病害快速诊断技术能快速获取隧道病害，有利于快速及时预防治理隧道病害；2） 通过隧道衬砌结构变形监测，结合位移反分析及应力反演方法，可准确定点隧道病害部位并提出针对性防治措施；3）诊断结果显示，顶压隧道拱脚及拱底的衬砌结构受力最大，提出对拱脚可进行嵌缝补强，对拱底可采用先回填后注浆的病害防治措施．研究成果对隧道病害诊断及其防治具有显著的工程意义及良好的经济价值，可推广应用．
Abstract:
Tunnel diseases seriously affected the stability of the structure so that the safety and reliability are greatly reduced, which seriously affect the normal use, even cause safety accidents of the tunnel. A rapid diagnosis and its prevention and control of tunnel diseases was presented. Based on the engineering support of a top pressure tunnel in Chongqing for application and the conclusions were as follows: 1) The tunnel disease diagnosis technique can quickly get tunnel disease information and rapid diagnosis, which is good to prevent tunnel diseases timely; 2) Through the tunnel lining structure deformation monitoring, combined with the displacement back analysis and stress inversion method, and can be accurately predicted the tunnel diseases location and put forward the targeted prevention measures; 3) Through the diagnosis, it can be concluded that the arch foot and bottom of the tunnel are the largest force parts of top pressure tunnel lining structure, the tunnel arch foot should embedded sewing strong, while the arch bottom can be backfilled to prevent and control the tunnel diseases. Research results of tunnel disease diagnosis and its prevention has huge engineering significance and economic value and can be popularized.
