| 摘 要： | 综合分析重庆市朝天门隧道施工竣工图、检测结果，结合实地考察，对该隧道进行安全性评级。采用有限元软件ANSYS建立合理的计算模型，分析衬砌结构目前的受力状况，验算隧道衬砌强度。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。同时亦可为其他城市老旧隧道的检测维修提供参考。

| Abstract: | Through comprehensive analysis of Chongqing Chaotianmen tunnel construction and completion diagrams and test results, and combined with the practical survey, assessment is made on the safety rate of the tunnel. The finite element software ANSYS is used to establish a rational calculation model, which analyzes the stress condition of the lining structure, and check the strength of tunnel lining. Therefore, the current tunnel carrying capacity status is given which is a strong theoretical basis for the follow-up reinforcement, and which also provides a reference for other old tunnel test and maintenance. |
