某城市老旧隧道质量检测分析

Quality Analysis of Old Tunnel of a Certain City

结合实地考察,综合分析了某城市老旧隧道检测结果,对该隧道进行安全性评级。分析衬砌结构目前的受力状况,由此,得出该隧道目前的承载能力状况,为后续加固整治提供理论依据,同时为旁边新隧道开挖对该老旧隧道的影响也进行了分析。本文的实例分析可以为类似工程提供必要的参考。

combined with on-the-spot investigation, the comprehensive analysis of the old tunnel test results of a certain city was conducted, and the tunnel safety rating was carried out. The stress of the lining structure at pres- ent was analyzed, as a result, the current status of the bearing capacity of the tunnel was obtained so as to pro- vide theoretical basis for further strengthening regulation, at the same time the influence of the new tunnel exca- vation on the old tunnel was analyzed. The example analysis of this paper can provide necessary reference for similar projects.
