摘　　要：随着对环境和景观要求的不断提高,城市明挖道路隧道建设越来越多。该文对此类工程的设计方法进行了系统的分析和研究。首先,就破损阶段法和极限状态法这两种设计方法,对相关规范进行了解读与分析;然后,分别对抗剪强度和抗弯强度进行了不同方法的计算对比;最后,得出结论,城市明挖道路隧道采用极限状态设计方法是合理的,能够达到不低于破损阶段法的安全度。With the continuous improvement of environment and landscape requirements, there are more and more constructions of urban excavated road tunnel projects. The article systematically analyzes and studies this kind of engineering design method. The article firstly interprets and analyzes the relevant norms for these two design methods of the breakdown phase method and the limit state method, then separately calculates and compares the different methods of the shear strength and the bending strength, and finally gives the conclusion that it is reasonable to use the limit state method for the urban excavated road tunnel, which can achieve the safety not lower than the breakdown phase method.
